What do feel is lacking in the AZ sound?
I have Confidence 3's powered by a Plinius SA201.
I had AZ's some time ago and didn't keep them long as I felt it wasn't a great match. The cables that I have had which I liked a lot were Analysis Plus Oval 8, Stealth Hybrid MLT, Gabriel Gold Rapture r and now Snake River Audio Cottonmouth Sig. Of those, the Stealth and SRA are the standouts in my mind. The Cable Co. has some SRA and Stealth around and I think that's an excellent suggestion. A lot of people seem to like the Nordost line with the danes, but it really depends on your ear, system and all the usual considerations.
