You certainly aren't going to rock the house with this amp, but if that was your interest--you probably wouldn't be looking at this amp anyway. If you are in a moderate sized room and listen reasonably close (less than 10 feet--I don't know if your room or speakers are conducive to that setup), you will probably be so engaged by the tube amp, that I doubt you will be looking for more volume. The only other aspect I would consider is the ohm (loading) of the speaker. I know you said 6 ohms, but that's nominal. You might want to be sure that it doesn't dip to some very low impedance in certain instances. That can create some difficulties for some tube (and other) amps.
