Thiels are great speakers that are not only power hungry but also quality hungry of all upstream components. I loved my thiels run with Mark Levinson amplification and direct from the Audio Aero Capitole CDP (no preamp).
Based on your statements, room size, budget I think you will be better of switching speakers instead of trying to find the right amp within your budget for the existing Thiels. You may find that after you get a better amp for these speakers, you will then be forced to upgrade your source and cables.
Jonathon, the Thiels are not bright by themselves, but they will magnify synergy issues upstream that with lesser quality equipment. This will make many former owners of them (Thiels) believe the weekness was in the speakers (which of course it wasn't).
Why not figure out what you want in a pair of speakers, offer the rest of your components up and inquiry what will produce the desired results you are seeking.
