I've got a trends amp, and it does a good job with my M3s and a line-source CD or DVD player. Hooking up my portable MP3 player isn't so good as the output signal is a little low.

I don't know if it would be enough power to be 'sufficient' for your needs or not, as I too would prefer some more power to really crank them up. But it is amazing what 5 or 6 Wpc can do.
