Who says a "serious audio person" would not "settle" for 65w? Tube gear is often low wattage. The need to blast the music is not an audiophile requirement. My 1050 with a powered sub gives me plenty of output. I have thought of adding a separate amp, but could not justify it's expense. I'm sure there are gains to be had, but don't underestimate the amp in the 1070 either.
