why don't I like it??

I would not pair adcom or aragon with klipsch... Go tube, or with a good small Class A amp... Some nice Hybrid, or even integrated hybrid.. You want to do some real justice and stay solid state with those speakers go with a mcintosh vintage or last 10 years....Plus being you say "separated" must mean you moved, and your current room and acoustics are vastly different than what you were hearing in the previous room and system..

Thanks for the responses. Yes I am relying on memory and the set up before was completey different. But....the sound is way different. So I don't think it's the room, components, wiring, etc...I think I'm trying to identify how to describe what I liked about the Adcom better. For example, the crunched guitars sounded much more pronounced. I think, in retrospect, it was a much "dirtier" sound. That have been what I liked. So would that sound be more related to better mids? It seems like to top is so soft on the Aragon. Almost like that part of the music that I liked isn't there anymore. Again, going from memory. The cd's I listen to are the exact same in most cases so I don't think it's the recording. Although the issue of loudness is interesting. I write and record music for fun and understand the concepts of compression, but never really thought of it that way. Most of what I record is electronic so I don't think compression plays the same role as live recordings, but I could be wrong. I guess it depends on the quality of the samples or plugin you're using.

Agree with Undertow, Adcom + Klipsch = Harsh. I have a pair of KG 3.5 and I believe that their sensitivity is around 94dB-- I am running mine on 25W tube monoblocks with excellent results.
