I am now 100% Audioquest Cheetah with 48v, and Audioquest Pike's Peak 72v DBS. Well my subwoofer is running on Panther 48v from my source to my pre-amp, but the rest is Cheetahs.
I have never heard cleaner highs, better midranges and voices having terrific clear and bodied (meaning that the voices sound natural and coming from a human body) sound out of my system.
I've tried in camparison Nordost SPMs, Taralabs Air and "The" series (loved "THE 1"s, but they were a bit overly dark and warm) and old audioquest lines (Minerals, again very dark and no high ranges). Among those; the Nordost SPMs came to the top of all of them in camparisons..and while I liked their sound in a friend's Tube unit, the SPMs lost to the audioquest in my system. SPMs were just hissy, tinny and unreal in my Solid State.
The DBS cables seem absolutely neutral, your mileage however may vary...
