"How can interconnects make a difference?"

Nonoise - For what is worth, the measurements and theory crowd (me included) would need to agree that interconnects can indeed make a measurable difference. In the non-audio world as well, you need to be aware of cable issues that can cause unacceptable attenuation when you want precise transmission of sensitive signals.

Jeff_jones... Traditional "measurements" usually report specific characteristics of the signal. The measured parameter can remain unchanged while other parameters change, and affect the sound. The significant parameter for audio is "how it sounds". and the best measurement instrument is the human ear. There is a way to make the ear measurement in a completely objective manner.

In the case of an interconnect...

1. Input a common signal to both channels of your system. You can use a real music signal.

2. Adjust gains and, if necessary, frequency response so that the signal measured across the hot terminals of the amps is zero ( a null). You can make this measurement using a meter or scope. or by ear using a headset.

3. Insert an extra interconnect in one channel.

4. Repeat the null measurement of step 2.

If the null obtained in step 4 is the same as step 2 the interconnect has no effect.

Way to hold your own Vance. Isn't education sometimes a bitch for those who won't listen.

Yeah, thanks for edjamacatin' us ignurnts real good in the ways of faith learnin's!

"Isn't education sometimes a bitch for those who won't listen. "

Seems like there is a contradiction in there somewhere? :)

Eldartford - Interesting test approach, thanks. To be honest I'm lazy and completely undisciplined on testing ic's & speaker cable. I just keep the ones that seem to sound the best (and don't cost that much). One of the vendors, maybe the name was something like alpha core, used to sell cables that were built like giant capacitors, two flat thin conductors with a very thin slice of insulation in between, would have been interesting to run your test on them as I think they might have been the most extreme attenuators in the marketplace. Surprisingly to me they (speaker cables were tested not ic's) seemed to screech the upper frequencies instead of squash them.
