It would be hard to find a topic more controversial and debated in high end audio today than the effect (or lack there of) of power cords on sound. The discussion of the contribution of power cords to the overall sound of a system has been discussed many times on this blog. When I first started my forays into this phenomena I didn't want to hear a difference, because I'm cheap and I'm a natural skeptic. However, my brand of skepticism is more of an “open-minded skepticism” so investigation was clearly in order. For those looking for an inexpensive way to do some experimenting HCM audio has a closeout deal on Audioquest AC15 power cords at an unbelievable price, $39.95 for a seven and a half feet power cord. As a bonus, they are fitted with WattGate/Marinco 5266, ends. Much nicer than what Audioquest originally offered as the standard terminations.
The AC15s includes a ferrite bead to help stop RFI and EMI from getting into the components. They will be replacing the Monser PowerLine300 on my Martin Logan CLS speakers. Audioquest has been my cable of choice for a number of years now. In addition to being one of the oldest cable companies in existence, they always make clear what makes one level of cable better than the next. Their staff is more than willing to make custom cables to any specifications and to complete and ship them extremely quickly. Take a couple minutes and read this short interview with Audioquest founder Bill Low.
