I've driven M3s with a 5 watt per channel SET tube amp, and with a T-Amp which doesn't put out much more than 5 wpc. The M3s are sufficiently sensitive to play at normal listening levels, and capable of playing at high volume with these low powered amps.

The problem is not the M3s sensitivity. Your Onkyo should be able to drive your M3s at higher volumes than you'd ever want.

BTW, the combination of a pair of M3s and a nice tube amp is just wonderful.

Something is wrong with your M3s or your set up.
