At one point I had All AZ cabling in my system, including the Silver II. Sounded fine with my Pass Labs amps, Cary CD, and Vandy 5A speakers. But after hearing so much positive feedback on Nordost cables, I decided to give them a listen. I first bought the Frey IC's and all I can say is WOW. So I sold off all the AZ cables here on Audiogon, and installed All Nordost. If you read other forums here, the difference between the Heimdall's and Frey's are slight. I recommend listening to both if possible and you can decide on YOUR SYSTEM. Zorro, cables do make a difference. It did on mine.
