Which floorstander for 25-30m2 room?

What is your tolerance of position? Can you accomodate a speaker 6 to 10 feet off the back wall?

Providing us with your budgets for both the speakers and the amp would be a good starting point for any suggestions.

As far as the speakers:

Do you want, (either now or in the future), to have matching center channel and/or surround speakers as an option?

As far as the amp:

Do you want tube or solid state?

How about a Remote control?
(Necessary, or not?)

Do you want a HT passthrough for 2 channel operation only?

The more information you supply to us, the more informed suggestions that we can provide to you.
