I am using a Dynaco ST-70 35wpc tube amp for my mains at the moment. They are 86db Proac diy clones. It is a great combination. They go plenty loud, even with only 35w, and I have to say that I can't go back to the 1050s sound. (Don't get me wrong, the 1050 is still a great piece of equipment.)
My next step is to try building and using 9wpc SET amps, but that'll have to wait on $$$. I wouldn't use them for HT, just for music, although I do use the Dynaco for HT.
Don't get too hung up on power.
