I was interested to hear that you were formerly using an Empirical Audio Off Ramp with your mac mini. I am currently using an Empirical Audio Pace Car (with Superclock 4) with my iMac/Sonos, and I am delighted with the combination. Now all my cd's live in the garage!
To answer your question, I replaced my Dynaudio's with Focal 1007be's. They are not as forgiving of problems in upstream electronics as my Dynaudio's were, but now that I've improved other components, they sound excellent. My system is posted if you're interested.
As far as the Rapture speaker cables, I was of course lusting after them, but they were out of my price range at the time. Hopefully, they are in my future. Thanks for the heads up about the new GG website - I had no idea.
I was unfamiliar with the AMR CD77. I just read about it - it looks very impressive. One question for you: Do you think it could benefit from a reclocker like the Off Ramp/Pace car, or is its jitter rejection that good?
