ML classics 9 and what amp ?

Recently I bought Martin Logan’s Classic 9s. At the moment combine them with an Arcam amp. But I guess there are better options out there. New or vintage. Up to a of €5000.   
Any ideas?

As these don't have active bass they need some grunt, you need an amp that's got some current and one that's stable down into 0.8ohms. and won't wimp out into this impedance.

For an integrated I would think a Gryphon Diablo-120 or 300 if you can afford it.
