Power cord? Why?
Sean - been at HE2003, but I'm back now. Regarding Goertz, these cables make a lot of sense technically. There is no way to get lower inductance than this. Not sure why Roger would be concerned about the amps. They should be able to drive these - ... 
Best speaker cables for B&Wn803 and Cello Encore
See the series of Speaker cable reviews by Bob Neill from Positive-Feedback - here is the latest issue:http://www.positive-feedback.com/Issue5/empirical7.htm 
Power cord? Why?
S23Chang - the equivalent wire gauge is what is important, not the gauge of a single wire. Low inductance cords are always made using multiple wire to get that low inductance. Resistance is only one piece of the pie. Inductance must be low as well... 
Power cord? Why?
Corona, I agree with you completely. My brother is a metallurgical engineer with 25 years experience. He has taught me a lot about this. This is why the wire needs to be fabricated properly and handled carefully in the assembly process. This is ho... 
Power cord? Why?
Sean - what I heard from Roger (via my dealer) is that he is concerned about the capacitance of the speaker cable resonating with the transformer windings of the speaker. I don't believe he is concerned much about the amp oscillating. I believe Ro... 
Best Upsampling DAC??? Need Your Advice Please
You should consider the Perpetual Technologies P3-A, which will kick the snot out of all of these with the right mods. The player is around $600 and the mods are around $550. 
New Perpetual P1/P3 configuration
KR4 - the mods include 11 traces that are cut, 12 components that are deleted and 18 components that are added, plus some point-to-point wiring. Non-trivial, I assure you. Takes at least 8 hours to do it with the right parts, equipment and a very ... 
Power cord? Why?
Iasi - I understand that Roger contracted Coda Technologies to design the Innersound amp for him. Same guy that designed the Coda and Continuum amps. I have heard from one of my dealers that Roger is not a cable believer, however he does spec a lo... 
Power cord? Why?
Eldartford - 99% of modern copper wire is oxygen-free. It's mostly marketing bruhaa.. There are a few examples of poor wire, but if you use a reliable source like Belden, Alpha or Carol, it's all good stuff.Now, if you want the best-sounding wire,... 
When using Maggies with Crossovers
I would suspect that custom cables would perform best, in a separated bi-wire configuration. 
optical or coaxial audio cable?
I am running both optical and coax from my Sony transport. They are indistinguishable now, but only after I did mods to the digital output circuits to improve jitter. With the right cable, the coax can usually be better, because it avoids the opti... 
Power cord? Why?
Hbarrel - I will not be driving from Oregon to Akron, sorry. BTW - Power cord effectiveness has little to do with how clean the power is.... See my FAQ page at:http://www.empiricalaudio.com 
Power cord? Why?
Iasi - I have had the Innersound ESL amp in my system for a couple of weeks. I know the design of this amp (by Coda Technologies) - no negative global feedback, strictly class A/B and lots of protection fuses etc.. - however, you have to be carefu... 
Power cord? Why?
Eldartford - you can buy hookup wire at: alliedelec.comCopper quality matters, whether it's power IC's or speaker cables. 
Power cord? Why?
Iasi - what type of power amp do you have? Does it have an AC input filter?
