Bluenose described it very well. I am using Hologram Bi-Wired for speaker cables and I found it to work very well tube amps. It is very natural sounding in my system, doesnt sound restricted like some of the cables that i've tried in the past. Music is evenly distributed through out the whole spectrum and the soundstage and imaging is very good and exaggerated. It wont be the best cables out there but you will probably spend a lot more money to get better results. The AZ cables are the best bang for the bucks, IMHO.
