For Sale by heartless corporation: number 3 Abbey Road



According to a number of sources EMI’s parent company, Terra Firma is trying to sell Abbey Road Studios in an attempt to stave off the wolves at Citibank. Sadly the studio is only expected to bring in something like tens of millions of dollars when the amount necessary to stop the $3 billion dollar loan from going into default is over $190 million dollars. If that's the case it's a bit like throwing the deck chairs off of the Titanic thinking that it will stop it from sinking. Also sad is the fact that many feel the “brand” of Abbey Road is worth more than the facility itself.

Abbey Road of course is most famous for having been the studio of choice for the majority of Beatles recording sessions and many early to middle period Pink Floyd recordings, though not “Dark Side of the Moon” as many sources are erroneously claiming. According to some sources EMI doesn't consider a recording studio an essential asset. That's not a joke by the way the music industry has lost it's way so badly it doesn't even see the value in owning a first class facility in which to record music. In this day and age a lot of music can be recorded using a computer and pro tools, many consider anything over and above that to be a luxury.

Customer Satisfaction

While this isn't something solely related to audio, I hope it serves as a reminder for home theater installers not to make a "goddamn maze" out of the wires behind your customers' systems. Especially when that customer is Hunter S. Thomson.

Delicious Sound

Haven't you ever wondered what would happen if you made a record out of chocolate? Me neither. Just think of what this thing would do to a decent cartridge.

Sort of Supergrass

The boys from Supergrass are going to have a busy year. In addition to a new studio album there will also be a new side project consisting of covers called The Hot Rats. The album was produced by Nigel Godrich so it should be a good one. Samples are available on their myspace page. Below is a video of them performing The Beatles "Drive My Car."

Roads to Rome

One of the most unique things about high end audio in the diversity of ideas present in the hobby. I've always believed that there is more than one road to Rome. While every path doesn't make sense to me as long the traveler arrives at the destination, which is musical enjoyment of course who am I to judge? When a designer looks at their products as something that is created, rather than simply manufactured that is always a good sign. After all if they aren't passionate about their offerings what's the chance that anyone else will be? After all we aren't talking about toasters or washing machines. Audio equipment acts as a conduit through which an artistic is conveyed. Just some ideas that these two videos inspired. Enjoy.

Them Crooked Vultures

In many ways John Paul Jones was the most under appreciated member of Led Zeppelin. Until recently his post-Zeppelin work has been pretty sparse but recently he seems to be making up for lost time. In the last couple of years he has released two excellent solo albums, "Zooma" and "The Thunderthief" and produced a couple of others. On Tuesday, November 17th his next project will be released. The album is a collaboration with Josh Homme of Queens of the Stone Age and Dave Grohl of Nirvana and Foo Fighters fame titled Them Crooked Vultures. It is currently available to stream through youtube.

Even more Beatles remasters news


In addition to The Beatles remasters being released on CD in mono and stereo versions Mojo recently broke the inevitable news that they will also see a vinyl release as well. Thus far there is no news on pricing, stereo and/or mono, or whether they will be sourced from the 24/192 digital masters or analog masters. But it's good news for record lovers everywhere. For those on the complete other end of the spectrum the catalog will also see release on a USB drive according to Reuters news agency, just in time for Christmas of course. Apparently, the release will be limited to 30,000 units. Probably in much the same way that the mono boxed set was "limited" to 10,000 units. In addition to the 320 Kbps MP3 files the drive will also contain the albums in FLAC at 24 bits 44.1 Khz. It's good to see that they are offering people something at higher resolutions than MP3. Now the only question is when will they release the music in 24/192 (possibly on Blu-Ray) because we ALL know that it's coming sooner or later.

The Beatles Mono vs. Stereo

There has been quite a bit of discussion on this blog about the importance of The Beatles catalog in mono. This video does a great job of demonstrating many of the variations.

Memories of Jim Thiel



Most of my fondest memories of Jim Thiel come from a factory tour in 2001. During the first night at dinner Jim, Kathy, and the higher ranking people were in a discussion about finish options, price points, shipping time, and other business matters while Ken Dawkins and myself were making non-audio small talk. Finally Ken asked me, "So what kind of receiver are you using with your speakers?" My response was, "Well, I'm actually using a Parasound P/HP850 preamp and an Adcom GFA5802 amp with Audioquest cables." Jim, who happened to be sitting next to me was obviously bored by the business talk and turned to me and said, "That's a pretty nice system." Jim spent the next 45 minutes or so having an in depth conversation with the least important person at the table, a kid in his early 20's that few people in the industry took seriously. It wasn't a one sided conversation either, he was interested in my thoughts and opinions as well.

The next day in the Thiel listening room Ken asked us to listen to the PowerPoints which our company had repeatedly declined to put on display. In fact myself and my co-workers were under strict and explicit orders to not listen to the PowerPoint speakers under ANY circumstances. The higher ups in our company had never heard the speakers but had decided based on size that they couldn't possibly be worth the money. At the time the first Thiel sub was still in prototype form, but nearly finished. I shocked my co-workers by saying, "I'll be glad to hear the PowerPoints, but only if we can hear them with the Thiel Sub." Well, one of the Thiel sales guys quickly said that it was Thiel policy to not demo prototypes. No sooner had he said that then Jim said, "deal." Needless to say on my return to the store myself and my co-work told everyone that would listen that we NEEDED the PowerPoints on display. We kept on the decision makers until they listened to them and in a couple of months we had them.

On the same trip I was struck by a sign near the door to the workshop that said something to the effect of, "Perfection is our goal, excellence will be tolerated." I told Walter that it was a great sign. His response was, "That sign isn't accurate, when it comes to Jim is should read "excellence will be grudgingly tolerated.""

A couple of years later while demoing a pair of Thiel CS2.4's for a customer I accidentally hooked them up to the 8 ohm taps of a McIntosh MC402 instead of the 4 ohm taps. The sound was remarkably better and I called down to Lexington to find out why, Sherry said she didn't know but would ask Jim about it and get back to me. A couple of hours later I received a 3 page email from Jim explaining that while he did not have direct experience with the amp in question that my findings did not shock him. He then went on to lay out an extremely involved scientific theory on why I heard what I heard.

Goodbye Jim



Today the sad news about the passing of Jim Thiel was announced. On the few occasions that I met Jim he was always very gracious. I can't think of anyone in the audio business that I respect more. He will certainly be missed. Like many others I'm sure, I only wish that I could have known him better.

The Thiel philosophy holds, among other things that a speaker should be time and phase coherent. Phase coherence is when two drivers in a speaker are working to create the same frequency and they are doing so by moving in unison. Time coherent means that the sound from each driver arrive at the listening position at the same time, which is made possible by the sloped baffle of his designs. The third major component to all of the recent Thiel designs was short voice coils held within a long magnetic gap. This arrangement has the advantage of keeping the voice coil of a driver within the magnetic field of the gap and dramatically reducing distortion.

To learn a lot more about the innovations and views of this founding father of high-end audio check out the following interviews. Also of interest is the March 1998 Stereophile interview conducted by .

Breaking down Thiel

As anyone who's been following the blog for a while knows I am a big proponent of Thiel Loudspeakers. They contain quite a few original design ideas and unique parts that set them apart from the competition. Gary from Thiel worked with on-line retailer Audio Advisor to create the videos below to discuss a couple of the things that set Thiel apart from it's competition.

The first video briefly describes some of the technical aspects of Thiel speakers that make them something special



The Thiel CS2.4 has been the apple of my eye since it was a 2.3.



Next up is the CS2.4SE, the new apple of my eye. What a beautiful finish!



The PowerPoint speaker is one of the most surprising and technically unique speakers ever developed. While being mounted on a ceiling it still manages to image where a normal floor standing or stand mounted speaker would.



The SCS4 might be Thiels most versatile speaker. It can be used as a standard left/right speaker, a center speaker, or for rears in a home theater application.



Last, but certainly not least is the Thiel CS3.7. The 3.7 is one of the most advanced speakers available today.

Wilco - Summerteeth on Nonesuch (vinyl)


Nonesuch records (Wilco's label after being dumped by Reprise for refusing to change aspects of their brilliant Yankee Hotel Foxtrot) has re-released the band's first three albums on vinyl with Summerteeth arriving in stores late last month.  Summerteeth is considered by many to be the album which finally shed them of their alt-country moniker which they inherited from Jeff Tweedy and bassist John Stirratt's former band, Uncle Tupelo with singer Jay Farrar. And happily, this double LP follows in the band's recent tradition of quality vinyl sound, which I was slightly surprised by since I never thought Summerteeth was particularly great, sonically, on CD (a copy of that CD [or maybe a remastered CD, come to think of it, I haven't checked] is included here, as well). I always thought the Reprise CD was overly compressed and crowded sounding. This LP, on the other hand, offers a much cleaner, unencumbered sound with Tweedy's voice high up in the center allowing much more room for the instruments to stretch out - especially the percussion and Jay Bennett's little sonic thises and thatses.  And while I've never heard the initial vinyl pressing from 1998 when the album was first released, opinions I've read are that this one is much better. 

And to think people have been buying the original LP on eBay as recently as last spring for highly inflated prices. It shows a little patience pays off - especially now that a new vinyl age is upon us.

Beatles Stereo Remasters

Both my blogmate and I agree; until the Beatles mono remastered box set arrives, it will require one thing and one thing only to tide us over - an ever larger box set.

I thought I'd post some quick pictures and impressions of the stereo Beatles remasters.

There are two songs ("Love Me Do" and "P.S. I Love You") which couldn't be included in stereo due to the lack of the proper mastering source, so the engineers wisely present the mono versions here rather than an inferior stereo mock-up.

The astute observer will note that, while the original UK Parlophone and Apple record labels are replicated for the 2009 disc art, Magical Mystery Tour uses the North American Capitol record label with colorband and silver Capitol stamp since it was first released in the US. I am of the opinion that all Capitol CDs should use this disc art, even today.

Attention was spent on detail with the aesthetic packaging of this boxed set. While the iconic yellow Parlophone logo was used throughout most of the Beatles releases on the label, from year to year and album to album, there were slight variations on the typeface and text placement. EMI/Apple made sure they were all replicated with the disc art (current logos and legal verbiage notwithstanding).

As for how the boxed set actually sounds, the first word that came to mind is "crisp." While listening to the first several albums, they finally sound the way they were meant to - full of energy, fast-paced, plenty of bottom end that sends McCartney's bass notes into your shoes and furniture, in-your-face guitars and vocals that scream out. On the later albums, once the engineers began paying a little more attention to how to properly mix for stereo (as opposed to the first couple of LPs with instruments on the left, vocals on the right, rinse, repeat), the sound begins to fill out with more elaborate arrangements and studio techniques, and these CDs demonstrate it far better than the 1987 masters.

Over the next several weeks, we're sure to hear all about how the engineers either created the finest digital remasters in the history of both digits and masters, or that it's "too loud" with "no sense of space" and how they've completely botched it for future generations, and that Sir Joseph Lockwood will be spinning in his grave - so I won't bore anyone with a long review of each album. As a huge Beatles fan who spent their own money, I'd be biased anyway. Besides, if you're reading this, you've probably read a dozen other reviews, already. Let me just say that they sound every bit as good as a modern CD made from the original master tapes can sound, which is long overdue. These remasters have successfully sent the 1987 CDs back to 1987. Without pristine early vinyl pressings and an expensive turntable and hi-fi system, you will not get a better impression of how the stereo records were intended to sound. Were the band's producer and engineers preoccupied with giving the recordings a huge sense of "air" and space? Not at all. By today's pop music standards, it certainly seems that way, but the Beatles were never exactly an audiophile's delight, either. The Beatles recordings are just some great sounding rock n' roll, pure and simple, and it's evident on the original master tapes. Now, for the first time, it's evident on CD as well. And for what it's worth, it's reinvigorated my hunger to hear Beatles music again.

Thursday, September 03, 2009

Audiophiles often bemoan the lack of a younger generation of audio enthusiasts. To be honest it's all a bit like Chicken Little claiming that the sky is falling. High end audio has always been a niche product and there is a good chance it always will be a niche product. However, the next generation of audiophiles are being created at this very moment by two completely different driving forces, the resurgence of the vinyl record and the iPod.

With records the kids are finding that they need help with turntables which leads them to stumble into the various on line audiophile forums and learn about much more than just how to properly set up a turntable and to care for vinyl. They are being indoctrinated on what to listen for in speakers, how to choose the proper amplification, and many more esoteric topics.

The iPod has made listening to music cool again and many of those kids are discovering the included headphones leave much to be desired and they are upgrading. When doing research on which new cans or ear buds they should get they are also learning about how to properly rip and encode digital music.

Below is a video about a young man that's fallen in love with records and reproduced sound. Hopefully this hobby will bring him many years of joy.

Yet more Beatles mono news



Just to make The Beatles mono-mania that's going on around here a little more absurd earlier today I received the following email from amazon:

Hello from Amazon.com,

Our records indicate you purchased a Beatles Mono Box Set, and we wanted to update you on its availability.

This new information will not affect your pre-order--if you pre-ordered a mono box set, you will receive it.

The manufacturer has informed us that they will be producing additional mono box sets due to high demand. While the box set remains a limited-production item, it will not be capped at 10,000 copies for the U.S. market, as originally reported.


That's good news for those who haven't already ordered.

George Martin Featured on BBC Radio 2

Since it's essentially Beatles month here at The Audio Explorer, I thought I'd link a very interesting program from BBC Radio 2 where record producers are featured. This week, it's George Martin talking shop about recording The Beatles, and of course there are clips of current engineers discussing briefly new technologies used in the upcoming remasters.

IT'S ALMOST HERE!!!



Both myself and my blogmate have been anxiously awaiting the release of The Beatles remasters box sets, particularly the mono set since they were announced. For those not aware the mono boxed set is limited to 10,000 copies in the United States and amazon.com is already sold out. Now being "limited edition" means nothing in and of itself however, since it is of limited appeal there is every chance that it will go out of print. So why all of the the excitement for the mono set?

George Martin and The Beatles spent days, sometimes weeks mixing the mono version of most of their albums. The stereo mixes were done usually by an assistant engineer. Sometimes it was even worse, the stereo mix was done by an apprentice engineer. Paul McCartney briefly mentions this in the extra material on The Beatles Anthology DVDs. Saying roughly, "the stereo mixes were done one day while we (George Martin, the producer and The Beatles) were at lunch." With the exceptions of "Yellow Submarine", "Let It Be", and "Abbey Road" the mono mix was the baby. The stereo mix was the bastard redheaded stepchild at best.

At first blush this sounds like a massive oversight. But as Mr. McCartney goes on to point out ". . . ninety-Eight percent of people were listening in mono." Stereo was new, many thought it was a fad and wouldn't last. Many Hi-Fi enthusiasts resisted it in the beginning. It meant a serious amount of money needed to be spent. They were forced to buy another amplifier, another speaker, a new preamplifier, and a new turntable.

Will the sound live up to the expectations? If the review on Tone Audio is any indication the answer is a resounding YES! Also of interest is an ongoing thread on the Steve Hoffman forum. Amazon has some interesting podcasts on the remasters on the right hand side of the page. In addition to two 10 minute interviews with two of the engineers involved in the 4 year project there are there are numerous half minute samples of various Beatles songs to enjoy until the sets ship. September 9th can't arrive fast enough!

8-Bit Miles Davis


Do you like Miles Davis' Kind of Blue, but can't stand all that analog fidelity or unencumbered studio ambiance. Then look no further than Kind of Bloop.


The listening room of George Cardas

Enjoy a quick video that presents a snapshot of George Cardas' listening room. What I find refreshing is that he could have any equipment that he wants, yet his system is very tasteful. If I'm not mistaken that looks like a double pair of Magnepan MG3.6. Those particular Maggies are one of the very best values in high end audio. For less than $5,000 they will easily compete with anything in the world when it comes to transparency in the midrange and extension in the high frequencies.

Kind Of Blue




Recently Miles Davis' seminal "Kind Of Blue" album turned fifty years old. It's quite possibly the most re-issued and praised jazz album of all time. The vast majority those accolades are richly deserved. Nearly any jazz fan that wasn't being a pretentious ass would recommend it as one of the ten best jazz albums for people looking to get into the genre. The work has been endlessly analyzed but that analysis hasn't stripped of any of it's power or magic. It's hard to put a finger on what makes it so special, but that's how it often is with things that transcend their genres and become part of popular culture.

. . .to boldly go . . .



This photo is all over the internet and I have one major question. Does the Wow and Flutter make every singer sound like William Shatner? Sadly, for many Star Trek fans this isn't available but I'm sure that some Enterprising (sorry I couldn't resist) fan will make one in his parent's basement. Hopefully, Paramount won't sue him when he does.

Another Legend Gone

Sadly many people haven't heard of Les Paul. In addition to being a great guitarist he was a great innovator and even an inventor. He invented the solid body electric guitar, thus greatly reducing the problem of feedback on stage. He also invented the idea of over-dubbing allowing one musician to record many parts for a single work. Not to mention his innovation of synchronizing a number of recording machines to allow for multi-track recording, thus making mixing after the performance possible. Modern recordings simply couldn't exist without his vision.





Les Paul (1915 - 2009)



Les Paul may not be the most celebrated guitarist of all time, but there is little doubt that he was the most important. Having not only paved the way for virtually every rock and jazz guitar player with his invetion of the modern electric guitar, he was also equally, if not more so, influential in the world of studio recording with the invention of multi tracking, overdubbing and other tape effects; all of which are still widely used today.


The Gibson Les Paul, a guitar so iconic it is rivaled only by the Fender Stratocaster, was designed in collaboration with Les and Gibson. While he may not have literally designed the entire instrument he made famous, Gibson recognized Les not only invented the technology, but through his own fame gained as a musician, made the electric guitar widely popular.

Guy Fletcher's Diaries

Below is a link to the professional diary of Guy Fletcher, a veteran keyboardist who has worked with Mark Knopfler (among many others) since the Dire Straits days and on every solo album thereafter. I find these posts to be very interesting, especially the technical notes and photos from the recording sessions of Knopfler's recent records.

Some highlights include seeing vintage EMI tube desks and tape machines still being used by Knopfler and his long-time engineer, Chuck Ainlay. Also, don't miss the pictures of George Martin stopping by to visit the sessions and to show off iPhone pictures from his frequent trips to Montserrat, or indeed, the revelation that Big George actually owns an iPhone.

Recovering History




One of the best ways to explore the history of music is to find out who influenced a given artist and explore their work. In this way Led Zeppelin, The Rolling Stones and Eric Clapton would lead directly back to Robert Johnson. For this method do work one very important thing is necessary. The recordings must be available. Many older jazz or blues performances are extremely rare and only available on 78 RPM shellac discs. These discs are relatively delicate and can be easily damaged. Unfortunately until recent to these historically important performances could be lost forever. United States Library of Congress has been working on a solution. They've come up with a machine that optically reads the information on an analog disc, similar to the way that a computer scanner works. Check out the NPR story, as well as some some before and after samples. Click here for the full story.

Bimbos and audiophile recordings

What do bimbos and audiophile recordings have in common? For the most part after the first encounter or two the thrill is gone. In the end they are great for impressing friends, but offer little to no long term happiness. I haven't heard the recordings from DirectGrace but they don't belong in the bimbo category. Even if the music does fall flat for some listener they will still be able to take satisfaction in knowing that their purchase helped those in need. Now that's long term happiness, it's a fantastic idea. Who among us hasn't felt at least a pang of guilt as we spent more on a pair of interconnects or a power cord than many people around the world make in a year? For that matter many of us own speakers that cost more money than people in the third world will see in an entire lifetime. Is it our faults? Not entirely. Can we do something to help change the situation? Certainly. Just some things to think about while watching the video.

It's In The Hunt

As one who is still very new to the active collection and enjoyment of vinyl records (I'm not counting using them as frisbees or surfing the basement carpet on them as a child), I've begun to appreciate the fickle, frustrating nature of the medium. Everything about the collecting, the listening, the tweaking, the maintenance and the hunt can be equal parts maddening and rewarding. I once spotted a pristine, mint-looking early Nat King Cole record at a thrift store. The jacket - shiny. The spine - solid. The inner sleeve - factory crisp. The record inside - "101 Strings, The Glory of Christmas." It's enough for me to cause a scene there amongst the rusty Faberware.

There are good days, however. Here are a few recent finds from a Goodwill. 

James Brown - I Can't Stand Myself (1967, King)

This is a very lively record with The Godfather of Soul in his prime doing what made him famous.




Tony Bennett - I Left My Heart in San Francisco (1963, Columbia)

This is a Canadian pressing (I'll explain my hang-up about this in some future post), but I couldn't pass this up at $1.99 CDN. This album was the first LP, I believe, with the hit title song which had already been released as a single.




Teddi King - All The King's Songs (1959, Coral)

This is valued at $60-$70, but more importantly, it's a great recording and is a very good record with outstanding performances by Ms. King.




Jimmy Rushing - Five Feet of Soul (1963, Colpix)

Jimmy Rushing was a blues singer who sang for Count Basie. His powerful voice and powerful personality is on display here. "Five Feet of Soul" refers to his nickname, "Mr. Five By Five." Five feet tall by five feet wide.




Cecil Payne - Performing Charlie Parker Music (1961, Charlie Parker Records)

Cecil Payne was a saxophonist who played with Dizzy Gillespie. He only had a handful of records as a bandleader, and this one is from 1961. It's also in great shape.



In the film American Splendor, Harvey Pekar, in an interview, commented on his time spent at garage sales looking for old jazz records, in search of that one title which will somehow magically make his collection complete. To paraphrase, just when he feels like giving up, he makes some find that whets the appetite all over again, and the cycle continues. I wouldn't draw too many comparisons between myself and Harvey Pekar. Besides, finding records at garage sales is becoming rarer and rarer. The energy spent (and weekend sleep lost) getting up on Saturday to check out garage sales which might advertise records on Craigslist are usually in vain since eBay and flea market creeps often contact the sellers early to try to get first crack at the bounty. Who wants to compete with that?

Luckily, I've rarely spent more than just a few dollars for a used record. Demand is low for analog, which is sad for the industry, but great for fans. Unless, of course, you're a Michael Jackson fan. After his death, Thriller began selling for over $100 for used copies on eBay. I'm glad I got a replacement copy for my 1984 original a few months ago from the 50-cent rack at a local record store. Of course, eBay is the worst place to buy anything, really, since prices are usually driven up by one singular moron with more money than common sense.

I refuse to be that moron.

Perfecting Sound



NPR has a wonderful interview with Greg Milner, author of "Perfecting Sound Forever: An Aural History of Recorded Music" which can be downloaded here. In the book Mr. Milner traces the development of recording technology from the Edison wax cylinder to the modern day. Based on the interview the books will probably a very compelling read.

Audio over USB




The arrivals of the iPod, iPhone, Airport Express and Apple TV have raised the bar of consumer expectations of convenience when it comes accessing their music collection. With hard drives being as cheap as they are and so many new DACs coming equipped with USB inputs putting together a DIY music server seems like a better and better idea every days. However, like many things in high end audio it's not as simple as it first seems. At least two major factors stand between the interested audiophiles and good sound.

  1. Jitter: In essence all of the "1" and "0" are present and in the correct order but the word clock that tells the DAC when to decode them is wrong. We're talking about fractions of a second here but our ears do pick up on it. Think of it this way. The world's best marching band all taking their time from a drummer with great rhythm vs. that same marching band with someone with no rhythmic sensibility. The musicians haven't changed, their instruments haven't changed, and the sheet music is still the same. But the rhythm won't be the same and things will start to sound sloppy and lax. Many of the new digital to analog converters are built specifically to reject incoming jitter are based on the Burr Brown PCM270x chips. That chip set has two major limitations. First it has a strong jitter component at 1kHz, which as misfortune would have it is smack in the audio band AND the frequency at which the human ear is MOST sensitive. Second, the chip is limited to a maximum sampling frequency of 48kHz which excludes it's use to transfer high resolution 88.2 kHz, 96kHz, and 192 kHz content. A better solution is a DAC capable of exploiting USB's asynchronous mode where the DAC requests the data when it is needed and therefore determining it's own word clock. Curently very few DACs on the market are capable of properly implimenting the asychronous mode because of the coplexity of the computer code necessary to make it work properly. Gordon Raskin, whose first career was in the computer world is one of the few people on the planet with a good understanding of bother sides of the problem. Currently his custom code is available in products from his company, Wavelength Audio and the upcoming QB-9 from Ayre.
  2. Re-sampling: CD's are at a sampling rate of 44.1kHz which means that every second is broken up into 44,100 slices with each slice being described by a series of 16 "1" and "0." Microsoft in their infinite wisdom decided that most of their products translate everything to 48kHz or 48,000 by adding essentially garbage in a part of the program called the "K Mixer." According to the Wavelength web page the "K" mixer can be by-passed or mapped through as it's called (proceed at your own risk) by the following steps. "Go Control Panel => Sounds and Audio Device => Select Hardware Tab => Select USB Audio Device.

    Click Properties Button => Select Properties Tab => Click the “+” to the left of [+] Audio Devices that will pop down USB Audio Devices.
    Select USB Audio Devices and click Properties.

    Check both Use audio features of this device and Do not map through this device.

Passion




Many times it is a struggle to explain to those not interested in high-end audio what drives the audiophile to sacrifice time, money, aesthetics, and domestic tranquility to achieve their goal of sonic bliss. Trying to describe any emotional experience to another individual is always difficult but the euphoria that is brought on by experiencing a phenomenal musical reproduction in one's own home of a favorite artist, many times long since dead is particularly difficult.

For the most part when trying to explain the quest to those who are interested in understanding I've repeated the same anecdote. When I was in college most of my friends were training as classical musicians which gave me the chance to hear live orchestral and string quartet music on a very regular basis. Though I 'm no expert. One night we were all sitting around and shooting the breeze while my stereo was playing a piece by Debussy in the background and one of my good friends asked, "Isn't this all a bit excessive?" while motioning to my system of the time. He was a huge Johnny Cash fan so I asked him, "When you pop in a CD of early Johnny Cash recordings into your boom box what is your goal?" He smugly replied, "I want to listen to a Johnny Cash CD of course" thinking that he had won the argument. My response was to say, "Then a boom box is an acceptable tool to reach your goal. My goal is different. I want to be transported back in time and space to 1955 Memphis, Tennessee at Sun Studios with Mr. Cash and his band 10 feet in front of me and Sam Philips a couple of feet behind me in the control room. To me a really great audio system is almost a time and space machine which should create a virtual reality experience." Instantly everyone in the room sort of got what all of the madness was about and from that day forward they respected what I was trying to accomplish.

Of course if this 20 minute documentary involving the Audiophile Club of Athens by Ken Barns had existed then I would have shown them this as well. It's a great peak into the passion, humor, and diversity that is the hobby. It's also wonderful viewing for audiophiles that have somehow lost their way and forgotten that it really is all about the music. Even though these gentlemen and I have had very different life experiences there is no doubt that the passion that we share for music and audio would be enough common ground to enjoy each others company for an afternoon.
