Agree with Liz. You've got a nice sized room. I'd be looking for 50 to 75 tube watts at the very minimum. I think a good rule of thumb with amps is to err on the high side. Of course, I'm not talking about 400 wpc mono-blocks. But in your case, I advise erring on the side of more watts.
Btw, I listen to classical music too. Just listened to Beethoven's 9th. Before that, Prokofiev's Symp #1. The drums rolls are really dynamic. I think a 34 wpc amp will run out of runway real fast trying to keep up.
