Acousctic Zen Sil. Ref. II and Absolute, anyone?

Florian, I have these in my system from my sources to the preamp. Before I purchased these, I auditioned a wide variety of ICs, including Synergistic Research, Transparent, Purist Audio, and Nordost (Red Dawns). To my ears, the AZ Silver Ref was better in terms of clarity and speed. I ended up purchasing them used here on Audiogon.

Please let me know if you have any further questions.

Florian, I have the SRII between my source and preamp. I compared them to Kimber KCAG, PAD Venustas, Cardas Neutral Ref, and an XLO (forget which one). Picked them because they had the best combination of clarity, speed, and soundstaging while retaining a musical presentation. I think, however, that what I found most interesting was the synergy aspect. I wanted to use PAD Venustas at this location and between my preamp and amp (which is what I use there). PADs in both locations were not nearly as good as AZ and PAD. Musical, but a touch too warm and smooth for me. The SRII worked for me, but YMMV.

I use AZ Silver Ref MkII between cd and pre. Matrix Ref MkII between pre and amp. Tried 2 Silver Refs and did not like it. Sounded artificial and too thin. However, a blend of Silver Ref II and Matrix Ref II is great. Even the combo of 2 Matrix Ref MkII ICs is a killer. But the SIlver/Matrix is just a tad bit more resolving and detailed without making any sacrifices.

Heard Absolute but not in my system. Can not offer much detail aside from the fact that the system sounded very good.

AZ cables, in my experience, offer the most without charging insane prices.

When you pull them from the box you know right away that they are really well constructed.
