'Don't think I can really capture the difference between the BiFocal's and KS 3033's in a verbal description without resorting to audio cliches that may not have a lot of meaning, especially recognizing that these things are system dependent, too, but generally speaking I found the 3033's to be a notch up in all respects. IMHO, the best thing to do would be to listen & compare in one's own system. (btw, I also use & like the KS 1020 interconnects -- and this is not an ad!)
