I use BJC and audioquest corals. I have also used Tara Labs which are way too bright sounding. I tried some high end Synergistic Research cables that one of our members sent me and they did not sound any better than my BJC's. They had a tad more transparency but less detail than the BJC's.

All I can is that when I auditioned the the Van Alstine 600R it transformed my system. The level of detail and resolution was superb. The transparency and sound stage was insanely good. Even compressed recordings opened up and sounded good. I thought about getting a 600R or 400R but they leaned a little to the bright side in my system and I don't want to have to get into rolling tubes again to bring it over to the slightly warmer presentation that I prefer. The Vincent amp can do that for me but after reading reviews and talking with Mr P, I think that the Pass amp may be the way to go.
