how can a line cord affect frequency response ?

Tvad: I wasn't asking for proprietary secrets. I was asking for some data indicating their cables improvement. For example, you bought a power amplifier for your stereo, certainly you asked it was tube, solid state, what power it has, signal to noise ratio, current capacity, perhaps you even talked to the manufacturer about their philosophy in design. All of this provides good data and information, yet is not proprietary.

Data is data, in my opinion. Whether the specs in the data correlate to improvement in sound is open to subjective interpretation.

I own a VAC tube amp. I am certain its specs measure significantly poorer than a $200 Technics HT receiver, yet I prefer the sound of the VAC, and I would bet most audiophiles would, too. Of course, there are also audiophiles who would prefer the Technics HT receiver with its superior distortion specs. It's all about what one hears, and prefers.

I appreciate your need to know measurements. I prefer to go with what my ears tell me. Call me crazy. Call me wasteful. It's my money, and I'll spend it as I wish.

hi tvad, i'm a renaissance man. eat your heart out !

MrT, the phrase “as a lawyer” implies you are one. The phrase, “if I was a lawyer”, suggests you possess the strong debating and analytical skills of a lawyer, which might enable you to win a debate with Guidocorona. For such a self-proclaimed learned individual, your misuse of the English language is confounding, odd, and perhaps purposely manipulative. It’s hard to tell. I mention this because the answer to the puzzle is germane to how one approaches your threads.

Frankly, at this point, I question anything to which you lay claim regarding your background or areas of expertise.

Oh, never mind.

Tvad notes:

Data is data(...)Whether the specs in the data correlate to improvement in sound is open to subjective interpretation.

I'd agree in principle with what follows -- BUT data and their correlation would be "objective". You probably mean that,
first, we formulate a theory of what data indicate audible differences and,
then we set about to confirm that theory (i.e. "objectivise" the subjective)...

Very commonplace info can be *indicative* of sound -- for example, yr VAC uses a linear amplification device (tube) whereas the Technics uses a switching amplification device... and the circuits are different of course as are the equivalent circuits of the system as a whole with one or the other component; also the design objectives (the engineering compromises made, if you will) in one case & the other are different.

For example, I (and probably others) would *expect* better sonic performance fm the VAC -- and poorer value for money

Just to repeat the obvious about "data"/"specs": it often depends on what one measures (and measures for).
Cheers

An afterthought: are'nt we looking for a "unified theory of audio"?
As in physics:)?
Maybe we can get Pr S Hawking on our board...:)
