I don't believe cables make a difference, any input?

Frequense-resonce is the last thing I would check up, it only shows energy-level and says nothing about purity/dynamics aso.

Btw; mods should act like..

Stick it, Scott. You know my position on this. AND how would I know that these cables are typically directional?

If not all wires are directional and the alleged differences in "directional" wires are due to how it is manufactured, than wouldn't a wire's "non-directionality" indicate it is less defective then the directional wire?

Also curious, if wires are directional, and AC current is not, how does directional wire do anything more than filter off DC offset?

Wait- you're saying that if you just use your ears and don't peek, the music changes timbre? Wow, the excuse bag must really be running on empty.

Well, how long has John been at it? Changing things, measuring things, listening, making mistakes? How long has he been actively training himself?

This is interesting. Listen to 6, 7 & 8. No17 is relevant also:

FORA.tv - Jonah Lehrer: How We Decide

When faced with judging and discriminating complex data, (and I think reproduced sound is complex - lots and lots of variables to consider), we don't and can't rely on consciously logical subjective activity. We have to go with "feelings" and apparently vague attributions. How did the guy know they were missiles and not planes?

I'm sure John can hear some things I can't and can reliably attribute them to specific causes. Whether or not he can always spot musical differences due to say, speaker cables, I don't know. I'd think he probably can, sometimes, at a rate better than chance.

I don't have a dog in the fight. I've never worried about the wire, but I'm a fanatic about really, really, really, really, solid connections at each end.

Linear frequency response is not indicative of signal "purity"?

Can you define "Dynamics" without invoking frequency?

Keep'em coming and we'll end up with a Wheatstone bridge....

This is like calling someone chicken to do something that is doomed from the start. Also, I have had people note wire directionality in one of our set-ups and it was changed

[john curl]

I would like to point out that when audio designers refer to quality wire, we don't mean something that is normally found at the hardware store, or the Belden or Alpha catalog.
We might think of Mogami as a good start, but there is better out there.
Once, I was sent some cable for a comparison like this. They were not BAD cables, in fact, they measured better than some more expensive cables that I had around. They were therefore bad subjects for comparison, because there wasn't much different about them. If I wanted to find differences, I looked into some of the cheapest and some of the most expensive wires, to find the real odd balls, that actually had a fair amount of harmonic distortion (compared to many others). It would be the same here. Trying to compare directionality in a random wire, might well be useless, YET with another cable type, very useful.

What "fair amount of harmonic distortion," John?

A variety of cables were measured, including some of the very same cables that you have measured, on a measurement system significantly better than yours and looking 20dB below where you were capable of measuring, and there was no harmonic distortion.

The only distortion seen was the residual distortion of Bruno Putzey's Audio Precision System Two Cascade.

Clearly whatever distortion you were looking at wasn't being produced by the cables.

I spoke to Bruno myself. We agree and we are both engineers. You should stay out of it.
