Fantastic sounding interconnects. I moved one up the AQ line but frankly not sure I heard much of a difference. These seemed a little more fluid and warm to me, vs a bit more detail with the Sky.
From a Stereophile review:
In any event, I enjoyed listening with the AudioQuest Cheetahs in place. I kept them there. Music flowed beautifully, and there was nothing musically unnatural or sonically pinched or distorted about it. With them, my system sounded lovely.
...with the AudioQuest Cheetahs, the sounds of the instruments popped out from the mix more believably during the lovely middle section of the Adagio, especially the few dozen bars where the strings are silent, leaving a single horn and some woodwinds to play. The silences in that portion were, again, blacker and deeper with the AudioQuests.
Graded conservatively at 8.
