+1 to Don's advice. It may be that you are just very used to, and happy with, the sound of your 601's. If you like them as much as you seem to, no point in changing just for the sake of change. On the other hand, you might like the Maggies even more! Doesn't Magnepan offer a money-back guarantee on one of the entry-level models? It's a direct-sale offer only (so the dealer isn't penalized if you decide not to keep them), but I don't remember who pays the shipping (one way or both). One other thing I would add is that your mention of having them about two feet out from the corners, firing into the middle of the room.....you don't want to do that with a fairly large dipole panel. The sound coming out of the backside will get sort of bounced around back there, eventually reaching your ears and mixing with the sound from the front side of the speaker. Could be a real mess. Plus, if the rear wave meets up with the direct wave at certain frequencies and in certain time relationships, you could get some pretty severe phase cancellation and really screwy tonality and imaging problems. Magnepan recommends AT LEAST three feet behind and to each side of their speakers. More is better, less is much worse. And if you DO have glass walls (and perhaps uncarpeted, hard floors), I sincerely doubt you would like the sound from Maggies in that room. But then, I would be surprised if ANY speaker would sound as it is intended to with all of those reflective surfaces. Can you put drapes across the glass, breakup the large expanses of wall with bookcases, CD and/or DVD racks, etc? Works great, costs little. Good luck on your search for great sound! Maggies can provide it, but only if they are right for the room and system.
