I have nordost blue heaven revII bi-wire, kimber 8tc bi-wire. comparing to the kimber, blue heaven wins hands down with more presence, darker background, tighter and slighly deeper bass, crisper highs, maybe not as warm as the 8tc but a lot more detail!
conclusion: nordost blue heaven--the best value model from the nordost flat line, is a true winner on my system. now I am going to sell my 8tc.
