Mono is the answer, if I can remember the question. I have a pair of Accuphase A-70's. These are true 60W Stereo full Class A , doubling all the to 1 ohm amps. 480W at 1 ohm stereo, 960W at 2 ohm bridged.
I almost bought the A-200 (100W mono) instead. I decided I would rather have the ability to HORZ./VERT. bi-amp and bridge. In the end my preference was BRIDGED.
Side note on how Accuphase does things. In their design, like the A-70 for example each cannel is basically is 2 amps in parallel. I said parallel not series ( bridging 60W becomes 240W, series ), buy running 2 amps this way main design gains are increased current, lower over all stress on amps per given output. Cost is the down side. These amps are a lot cooler to the touch than any other Pure Class A amps that I have come across.
This product may well be as close to the amp " erik_squires " says you can not find. Well, for under lets say $100K, just saying.
Any how, I would say this if you go stereo, get something bridgeable to keep your options open. If you have the funds down the road, yes in my opinion there are gains to be had in power and presentation, etc.
As for Thiel on the whole I would agree but once you have reached the Top of the Line, you can still take it further. This is the nature of upgrading, there is always another step. Perfection is unattainable, nothing is the best. Is trying to reach perfection a waste of money, well that is a question of ones values is it not.
