Thiel CS 1.6 vs ProAc vs ?

Thiel are generally (at least the ones I've heard) lean and hyper-detailed, definitely on the 'gray' side of things. ProAcs (2.5s, 2Ss, etc.) are generally fuller and warmer but less detailed, really on the 'cream' side of things. Thiel makes suberbly built and engineered speakers but they require careful component matching. The right ProAc can sound good with any number of tube and SS pcs.

Your pre-amp, by the way, is on the 'cream' side of things (kind of sounds like the color of it's front panel), and the Aragon is on the 'gray' side. Interesting match.

Actually, depending on how much you want to spend, Harbeth C7ES-2 is a damn good speaker with superb musicality and natural detail. Should work really well with the big SS amp but you'd need stands - very important with these or any other stand mount.

My room size (22X15) is one reason why I'd prefer to stay with a full range speaker. A speaker I've read about recently is the Joseph Audio RM22si MkII. Do you have an opinion about this one?
Your statement about my electronics is interesting. My view of the Aragon is that it is a neutral and powerful amp and that the C-J is a little less neutral (warmer) pre-amp. Are you indicating that I have an incompatibility or that the two units are fighting one another? Again, my hope was that I would be able to use this combination with the Jolida source and purchase speakers to produce a reasonably detailed sound (especially for vocal and small group instrumental music), also with a fairly neutral reproduction of the sound spectrum, and ultimately an involving music experience. I realize I may be asking for a lot in this price range. I'm hoping that my eletronics combination is not "flawed" so that I can't realize my goal.
