First off, these are both amazingly revealing electronics, fast, musical, the best I have experienced by a large margin. At this level of performance, it really isn’t a matter of how much bass, treble, detail, dynamics etc they have -- they have it all. The question is, "what are you looking for"
I used to have the base models FM acoustics pre, power, & phono
and listened to a CH integrated a few times — but not in direct comparison. Strangely, I didn’t experience any of the attributes ebm mentioned above, however. I might say that the CH was slightly brighter, but I would be nitpicking; the CH is contemporary in that it has everything included (phono, digital input, etc). The riaa on the FM may have been better (i.e. more detail, clarity & sense of sudden dynamic contrast), but I would be nitpicking again...
