Denf, I have the Solo Crystal interconnects and Oval 12 speaker cables and am very pleased with them. They sound a little less etched than the Silver Ovals. I don't know if I am qualified to comment on the AZ cables because I have not heard them. However, the AP Solo Crystals utilize the same Zero single crystal metals technology as the Acoustic Zen with the added benefit of the Hollow Oval design. I believe that AP came up with their Solo Crystal to compete with the AZ and Harmonic Tech cables. For your information, according to the people at AP, the cable design is more important than the materials used. With the same single crystal technology and the Hollow Oval design, I can't see how AZ could be much better. As you know, AP has a 30 day trial option. Jim
