I did use the AZ Silver Reference. It's a good cable and better than the AZ copper cable which I didn't care for. I don't think it is as transparent as the AQ cable and did seem to add a touch of silvery glow to things the AQ didn't have. With the wrong electronics, it could add a touch of sibilance to things (especially digital playback.)
Honestly, I've found sibilance to be more of an issue with the electronics than the cable itself. For example, I had Kimber KCAG with a Bryston B-60 integrated amp and it had sibilance. I blamed it on the cable but as it turned out, the Bryston's sibilance was just being enhanced by the Kimber. It was really there the whole time.
