I use the Blue Heavens to bi-wire a pair of Sonus faber Concerto Grand Piano speakers in my main two-channel system. I think they are extremely transparent and will show up associated equipment, warts and all. They are slightly leaner in the low frequencies, but much faster than my previous cables (Yamamura Churchill, vdH). From the lower mid-range up, though, I think they are hard to beat for the price.
Rest of the system comprises a Krell KPS-20i player and Krell KAV-250p/KAV-150a pre-power, connected with Blue Heaven balanced XLR interconnects.
