Why do audiophile always perceive different as better? This is the case with both the A-S2000 and the 2100. Both are very fine but with slightly different sounds. The A-S2000 is far better based on it's current used market price. They are much more alike than different to justify the massive price difference. I own both and really have no preference other than the minimal convenience the remote provides with the 2100.Both make wonderful music! If you really want to hear a difference, EAT LESS CHEESE!
