Could you explain why the e.g. 2.0 V out of a source becomes a different kind of 2.0 V when it leaves the pre amp?
I agree that anaemic tube amps are never a good idea. However, this room is only 10x12 feet. I use a 2x100 watt rms at 8 Ohm Quad 405-2 into my P3ESRs (i.e. some 130 watt into their 6 Ohm), in an 18 sq m room, and that is fine. It will not bring down the walls, but no small speaker ever will.
