Another Interesting Video from Paul

A while back PS Audio's Paul McGowan bought some gear to make their "Coal to Coltrane" DVD and has been making interesting smaller videos ever since. The new one discusses what high resolution digital audio is, why it's better, and how we can get it into our systems. It's a good way to spend the next 9 minutes. Enjoy.

Audio in Unexpected Places

The audiophile pursuit is so isolated from the "real world" that it's always a pleasant surprise when there is a mention of the hobby in the main stream media. Below is a clip from Mystery Science Theater 3000, know as MST3K to fans.



Unfortunately the robots reactions mirror the attitudes of the general public a little too closely. My favorite part is when he is seen applying the green pen tweak to a CD. Mike Nelson is an audio enthusiast having written for Home Theater magazine in the past and having seen selling used gear on Ebay. I wonder if the system that he named in the clip was his dream system or his actual system at the time. Being from Minnesota he really should be have mentioned Magnepan and Audio Research to give some good people who make stellar gear a bit of free publicity.

PS Audio strikes again





PS Audio has a habit of coming up with innovative, yet relatively affordable high end audio gear. Their newest transport reads a CD into a memory buffer in an effort to virtually eliminate jitter. The built in display is capable of showing cover art in addition to the standard information normally displayed by a CD player. The unit has been in development for quite some time, above is a picture of the original prototype.

Also of interest is the matching DAC which has an I2S input capable of much lower jitter compared to the more standard digital connections of optical, coaxial, and AES-EBU which are all based on S/PIDF. The built in volume control is also a nice touch. For those who use only digital sources it would allow them to do away with their preamp entirely. Due to the fact that the DAC can find music files on networked hard drives it can also be used to put together a first rate music server. Add all of that up and it's a virtual swiss army knife.

Who better than the man himself to explain it all? Paul McGowan tells you all about them in these two youtube videos.

Panamax vs. Monster power conditioners.



Monster power conditioners use MOVs, which have a relatively limited lifespan. After the MOVs are gone MANY times the units continue to pass current to the equipment meaning that the next surge could destroy the connected gear. The Monster units do have a light to indicate that they are no longer protecting the equipment but who wants to depend on a light that they can forget to check?

Panamax uses an avalanche diode that acts almost like a flood gate. It opens when voltage is above or below a safe area, then starts testing the voltage. After the voltage is back within the normal range for 7 seconds Panamax units allow the equipment to receive electricity again. When an avalanche diodes fails they are stuck in the "open" position 99.9% of the time. Meaning that the equipment receives NO electricity so the user knows that the power conditioner needs to be replaced.

Panamax specifies that MOVs are 1000 times slower then their avalanche diodes. At trainings Panamax regularly does a demonstration where they hook up a Panamax and a Monster into a device that can create spikes, then into each unit they plug an illuminated lamp. Both units are then hit with a 150 volt spike. In the 10 or so demos that I’ve attended I’ve noticed two things. First before clamping down the lamp plugged into the Monster grows momentarily brighter. A sign that is letting the beginning of the surge through before clamping down. Hence the potencial for damage to connected equipment. No increase in the brightness of the lamp plugged into the Panamax is observable. Second, I’ve NEVER seen a Monster live past the third “hit”. Twice they began to smoke, once a small fire began. The Panamax products have lived through 10-15 hits before they go on with the presentation, they don’t fail mind you the presentation just moves on because they’ve proved their point.

From what Panamax says other surge devices using MOVs will act in a similar manner. If you are considering things up market from the Panamax products Transparent Audio’s power conditioners also use avalanche diodes and offer some of the best power conditioning that I’ve ever heard. PS audio’s new power conditioners use something in addition to an MOV. They claim that these two devices in tandem are better than an avalanche diode. They may be, for me I look at how these devices work in the long term (ie years) and their products are just too new for there to be a body of empirical evidence out there, one way or the other.

For my own use I've used the original version of Panamax's MAX-5510 for about 4 years in my high-end two channel system. For my computer, TV, and AV receiver I use one of their cheaper units.

Pure Power

For the last couple of years PS audio has been making some of the most exciting and innovative power conditioning products on the market. In the video below PS audio's founder Paul McGowan takes us on a tour of their Power Plant Premier.



I had a Power Plant Premier in my system for a month recently. The drop in the noise floor was unbelievable. The recording that sticks most in my mind was Paul McCartney's "Unplugged." The tonal shifts in his voice as he would move his head to talk to either the audience or the band were always audible, however with the Power Plant Premier the changes were astounding. Sound staging depth was also dramatically increased throughout the album. One detail that I had never noticed before nor have I heard since was the sound of McCartney shifting his feet between songs. Micro dynamics also became much more evident.

PS audio is currently offering a free DVD entitled "Coal to Coltrane: a Brief History of Power." Anybody that is interested in high end audio should request a copy. It's full of insight and anecdotes from Wes Phillips, Michael Fremmer, Robert Harley, and many more. The documentary not only demonstrates the basic principles of electricity it also explains how and why we have the electrical system that we do today. The program isn't a fluff piece selling merely PS audio's products, in fact it rarely mentions their wares. It could easily be shown on PBS, it's that educational and historically informed.
