Try the Harmonic Technology's Pro-9 Biwire. It is as good if not better than most exotic cables out there and the price is reasonable as well. Very musical & detailed.
Bi-Wire Speaker Cables Suggestions
I have all Classe components; a CDP-1 CD player into a CP-47.5 pre-amp into (2) CA-150 amps into my speakers which are NHT 3.3's. I want to know what speakers cables would work best. I want to use bi-wire cable to keep a clean look (assuming the leads will reach between the amps which have connections about 1 ft. apart). Also for the reasons of "cleanliness" I dont't really want cables that have "magic boxes" on them, i.e. MIT, Transparent, etc. The Kimber Bifocal XL's look nice (haven't heard them), but are ridiculously expensive.
