I realize I have slightly different models, but perhaps this will help anyway.
I have the acoustic zen satori & until two days ago the acoustic zen silver ref i/c. The satori walks all over the AP oval 9 copper cables I had. The silver ref i/c is one of the best i/c's I've heard. Not ultra-transparent (like upper end nordosts), but nicely detailed, harmonically balanced, and wonderful to listen to. They remind me of vandersteen speakers.
