Why Expensive power Cables when Romex behind Wall?

It's interesting that no one seems to disagree with what I said earlier in this thread, and no one is saying that expensive pc's are a good investment. That must tell you something. Tom

Trich727, you must have somehow completely overlooked my post.

There's something that Bill Parish (GTT Audio/Absolute Power Cord) taught me: "The last eight feet (of power line) are the most important."

A year later I have a very clear idea on this subject--and also why cryogenics is the most cost effective treatment. It's in the very last feet that the electric particles/waveform gets shaped prior to entering the audio component. As such, there will be a profound influence on sonics. Tice TPT, cryogenics, Bybee filters--they all work on some aspect(s) of reorganizing the particles/waveform prior to entering the audio component.

This has been THE most important lesson I've learned since coming back to the hobby after a five to six year break.

Psychicanimal,

Would you please provide references/documentation for this statement: "It's in the very last feet that the electric particles/waveform gets shaped prior to entering the audio component."

Don't hear more than I'm saying. I'm not challenging the statement, I just want to know its scientific basis, as opposed to the opinion of the individual that makes and sells the cords.

Many thanks,

will

"It's in the very last feet that the electric particles/waveform gets shaped prior to entering the audio component. As such, there will be a profound influence on sonics."

This is nonsense and technically incorrect. Just because some saleman says does not make it true. The network created by the conductors from the transformer and then from the panel to the outlet and then from outlet to the component all contributes. You can easily perform a SPICE simulation on this simple model.

There is nothing magical about the last 6-10 feet of wire unless perhaps it has a transmission-line termination in the plug or on the cord. An added network of this sort COULD prevent/reduce high-frequency reflections or resonance on the overall wired network. Whether transmission-line effects occur and if so, whether they would affect the delivery of power is debatable and difficult to prove.
