Today I took Gregg Straley's speaker cable to a dealer store compare with a pair of Audioquest CV-8, I have running Gregg's cable through my system for just over 40hrs (less than the 60hrs recommended by Gregg). The system that we use consisted of Cary 303/300 HDCD player, Paradigm Studio v100, and Cary SLI-80 integrated tube amplifier.
The difference in sound between the two cables is NOT subtle, it's MAJOR!
If I'm going to use a frequency response curve to describe the two, they may look like this:

Hence in comparison, the AQ CV-8 sounded more open, spacious, more extended and transparent high and more dynamic/thumping bass.
I saw the smile on the dealer face (idiot!!

), I'm taking Straley cable back and try to break it in for a few more days, then I will borrow the AQ CV-8 back to compare it in my system.
