thanks again for all your advice, it has been really helpfull.
It turns out that I have a faulty T-amp. My friend's T-amp drives his m22s fine, and plenty loud. We also compared the t-amp to his arcam delta 290 (all would agree a "real" amp) and the m22s sound equally great on both, no audible sound quality differences. So it seems that T-amp can drive the m22s just fine, when it is working. Mine keeps on cutting in and out on the right channel, etc. So, for me, the m22s are a DEFINATE keeper. The T-Amp will go back to be exchanged for another T-Amp (it does sound TOO GOOD for just $140), but I am now also on the lookout for a deal on nad c320 or arcam a65, as the T-amp doesn't inspire confidence in its reliability.
