Perhaps some of the results, if real, could have been attributed to level differences due to resistance being so far off from the other cable which we don't know anything about.

Besides you taking extraordinary measures to have cables of such quality that you can alter just one parameter at a time, you need equivalent listeing evaluations too, highly controlled with significant results.

Can you send the same cable to your other source? Do they do DBT listening? Another listener who can?
Yah, I did mess up...no resistance measure..oh well..

Listening test...the only controls were that the listening system is one which is familiar to the listener..and the rest of the system was untouched..but it was a sighted session..he put the wires in, then listened..

The purpose of the initial test is to start to develop a baseline..which I will explain as it progresses.

Of note is the fact that at low levels, the sound appeared correct to him..but, as he increased the power, the bass fell off..both of us have the impression that resistance was at play here..since bass is by far the biggest power hog, it also seems logical. But, since the differences cited were "seen" to be different at different levels, absolute level isn't a player here..I'm rather confident, without asking, that he does not have a loudness control..

His description of 3 dimensional soundstage issues were by far the most detailed description I've come across...and it raises a whole spectrum of issues which are extraordinary..The transforms required to get from two point sources at different distances (the sax and washboard) but in the same angular location, to the two independent virtual images created within the mind by two point sources (the speakers) are not going to be easy math, so I'm thinking about it..

The questions this result raises are several: first, what cues are being used to establish distance from a listener to a virtual image, second...of those cues, how does temporal shift left to right affect it..third, how does a "wire" affect those temporal relations..

The issues clearly do not fit within a 20 to 20Khz bandwidth model, nor is it simple phase accuracy...It's not a frequency response issue, at least at low levels, and I'll beef up the wire to see if that changes the higher level bass impression..

Yes, it's all subjective..yes, it assumes a level of trust and reliability..and yes, I will continue to work with Ted in this fashion, as I seen nothing to indicate that he will be anything other than completely professional and honest..on the contrary...I asked him to do some work for me as a favor, and he provided impressional detail I would not have been able to.

E-stat had pointed me to another on the east coast, but that person never continued discussion..my friend the boat guy...lost cause..he prefers tossing money into that big hole in the water.

DBT will come with time, but for now, I am trying to establish what it is that is being heard. these initial rounds of tests, I believe, will provide a better metric for observing differences.

Gene is chompin at the bit to measure the remaining cable..I will arrange for that. But he does not DBT, simply electrical eveluations. I wish to test my assertion that my cable has no skinning inductive loss up to at least a megahertz..I designed it so to eliminate skinning as a factor, and to keep the inductance low..

I'll start a new thread to cover this ongoing topic..later today, perhaps.
