Reb1208 : I had the 15 not the DR15. I would agree with you - to my ears the 15 sounded more dynamic and "liquid" than the CA200 and the CA201. I had the 15 driving a pair of NEAR 50Me's (early 90's - one of the first full-range all metal-driver speakers available for those of you who may have forgotten ;-) and it did a great job of taking some of the edge off the 50Me's.
The CA300 that you owned is a much better amplifer than the 200, and in many respects I preferred it to the CA 400. Incidentally I didn't find much difference between the earlier version of the CA200 (heat sinks at the back), the newer version CA 200 (heat sinks on the side), and the supposedly revised CA201 (from what I hear the revision pretty much amounted to a new faceplate). I'm not really familar with the electrolytic cans the 15 used vs. the CA200/201, but your theory could be true. Just like other manufacturers I'm sure Classe changes part values all the time depending on suppliers, new technologies avaialble, etc.
I'm curious about the new line of Classe equipment - hopefuly they won't suffer the same fate as Mark Levinson did. From what I hear the company will retain full control over design and development, so hopefully this won't be the case. I won't be surpised if B&W pushes for a wider pipeline for home theater products.
