I owned the 7100 and have heard the 2250 but I didn't compare them directly. I thought the 7100 was very good but if you are into very detailed sound, you won't like it. For both of these, you have to be careful what speakers you pair with them - you don't want a soft sounding speaker. I think your Totems will be fine.
I personally vouch for the 7100 - it has terrific power reserves and it's probably the most coherent amp I have ever had. The music flows in a totally composed fashion. The 2250 is a little drier sounding...not as sweet as the Mc. The 7100 definately sounds like tubes but has bass slam that is very impressive for the amp's size and specs. Good luck! Arthur
