Acoustic Zen Silver Ref vs. Kimber Select 1030

Dmailer, thanks for your reply. In fact, I am using AZ Matrix reference IC between Krell 300i integrated amp and Sony 777ES. I am also using AZ Hologram biwire for B&W N805. AZ Matrix Reference replaced Transparent Music Super XL version. Compared with Transparent which is very lifeless and flat, AZ matrix wrought substantial differences in my system. Music takes on three-dimensionality, layering, and precise imaging. I can feel or see through a venue where music is being played. So, I am completely satified with the matrix. The reason why I posted this question is that I coud use more air, openness, and transparency. I am not saying that the Matrix is not airy, open, or transparent. It is very good in those aspects, but I could push a little further. I have not tried AZ silver which appears to be as great as Matrix. I heard great things about KS-1030 as well. I might try one or the other in the future.

Did it take a long time to break in AZ Silver reference in your case?

Thank you all (Eagle, Gpalmer, and Dmailer) for your informative responses. After I posted my question, I got a hold of a pair of AZ Silver Ref. from a seller on AA. The seller claims that the one that I purchased is the lastest version. I will double check with the seller about the information. I will try the cable and let it break-in for a while to see if it will bring a kind of improvement that I like to hear. I will report back for sure esp. comparison between Matrix and Silver ref. Thank you again!
