I sold Krell for 6 years.My boss didn't have them but for friends I got Cardas (as much as you can afford) tames the metallic mids inherent in Krell all the more to enjoy the fine highs and great bass grip.Cardas softens the nasties that make Krell (A or A/B) sound metallic or "etched".Avoid any cables (like MIT) that makes mids "pop" which a lot of people think gives them more because of the "pop" but in fact just roll off frequency extremes but this is for all speakers and my gripe about all cables manufacturers who give less info rather than more.I like Kimber for value but Cardas is great for Krell.
