I have a pair of these beasts:-)) too
Even with the DA80M (old class a) you've not enough power. Look for DA100M or best DMA x2. Or someth#ing like a Accuphase p600 ...
You need really power to drive these.
But then you are in heaven:-))
To my knowledge there is no speaker out there with which can compare in the mids ans soundstage.
