I'm using a modified T-Amp in a large family room (15' ceilings, stone floor open to a large kitchen), speaker output from T-Amp > Velodyne CHT10 subwoofer, line out from sub > a pair of Michaura M55 (like the M22). Source is an upgraded Ah! Njoe Tjoeb (upsampler, Siemens tubes). The sound quality is excellent at low, or normal-to-high (for me) listening levels, but if you push it a bit too far the sound quality breaks down. Within its comfort zone it is an unbeatable value with sound quality which matches or tops amps costing 50 times as much.
I recall pmbuko posted a comparison with a receiver and found the T-Amp performed like you would expect a $20 amp to perform. He must have tested a bad one. This thing is a joke it's so good.
