My Thiel 7.2 is not lean at all with great midrange and full body. It can sound very thick, depending on the gears you have. I suggest tube preamp and high power solid state with the Thiel 7.2. So have you tried anything yet to tweak out the Amati?
At the moment I'm finding the midrange in the Amatis very thin and light. I'm not sure if they are meant to sound like that or not. Especailly at higher volumes. I recall my brother used to have a system with SF Extrema driven by Krell KSA300, Levinson pre, and Wadia cd, and the sound was exceptional. I'd had hoped the mid of the Amatis would be the same if not better.
My main point is if the Extrema can work so well with solid state, then I shouldn't have to move to tube with the Amatis. I know it's stubbon, but there are enough speakers out there that I'm sure I can find one which works the way I want with solid state gear.
However it sounds like neither the Amatis or the 7.2s match those.
I have tried positioning the speakers as others have suggested, but it made a difference to the imaging, but not really the tone. I think I also have a problem with the room.
At low or moderate volumes the Amatis actually sound alright. I just want to play it very loud, which I recall the Extremas were able to do.
I guess I'll keep looking. I quite enjoy the road to finding the ideal system.
