No problem there! I tried to be somewhat thorough; also trying to predict question having to do with my test. Now I will admitt I could have done more, but why? My test I believe was thorough enough. After all I love my interconnects, and do not regrett any of the choices I have made in assembling my system.

As for your frequency response question; based on manufacturers specifications, this to was not an issue.

The test was fun, the problem is that my friends think I am even stranger that they thought I was before.

So you believe interconnects can affect the sound of ones system?
WOW. If your line stage is passive, you have a problem right off the bat, especially if the output impedance is variable with the volume control. The passive setup will certainly roll with cable capacitance differences differently.

What else you neglected to mention?

SPL meter is not sufficient to match to .1dB level differences, sorry. You need a volt meter, measuing the voltage difference at the speaker terminal, one that is accurate at such frequencies and is able to do .01 v differences.
But these are some of the small issues.

I bet your passive pre is the culprit!!!
