Why Expensive power Cables when Romex behind Wall?

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.

¿Nonsense?

1) I'm hearing it.
2) I thoroughly read Bybee's website and non-mathematical explanation.
3) This is also congruent with George Tice's viewpoints.

I have no electrical background, but I had a Materials Science Engineering roommate in college. Everything they do is related to crystal structure. Cryogenics deals with ordering (reducing the entropy) of the crystal structure. Electrons behave both as particles and as waves. Noise floor in the conductor lowers as a result of rearranging the particles in space--that's a no brainer to me. There's a lot we don't know for sure...

A few weeks ago I was studying for a pre-employment chemistry test and while reading about orbitals and crystal structure it all clicked in place.

What are the basic scientific activities?

1) Observation (hearing, smelling, etc)
2) Search for regularities
3) Investigating the why
4) Communicating findings

Will, just send one of your power cords that you have two of for cryo and do your own experiment. Other people have been doing it and posting their results in other forums.

Now that Sean has a ONEAC noise reading device we'll be able to conduct some experiments on noise control tactics and get numerical data.

Until then, don't knock it 'till you try it...
