Balanced Interconnects, Which ones???

If money is a factor, Audioquest Lapis can be had for less than the Diamond, and will get you nearly the same warmth. I use Lapis, unbalanced, in my system and the sound is excellent. I agree with the post above about the silver helping to preserve the signal the best.

Nordost Quattro-Fil

I just made myself of balanced cables out of Kimber PBJ and they stand up to anything. Balanced is the key, skip spending loads of cash...

Definitely balanced with Krell. Try HomeGrown's Silver Lace. I hear good things with those cables and Krell gear.
