Best amp to drive YG Acoustics Hailey 2.2

I just ordered the Hailey 2.2s and was curious to hear what others are driving them with. YG uses D'Agostino in their listening room. I've heard good things about pairing them with Ayre and Luxman. Any other suggestions or thoughts? Would a Gryphon Diablo 300 drive them sufficiently in a larger room (20'x30')?

I currently have a Mac C-2700 and MC462...also have a Rel No 25.

Any help or suggestions would be greatly appreciated.
I’ve owned the Luxman, Rowland 625, and Pass x.8 on Haileys - the Rowland was the best although Luxman monos would probably be very good (stereo wasn’t enough).

I ended up using Ampzillas myself in the end.
I have been thinking about this.  The other brand I would look at is AVM.  The 8.3 line has a tube input stage that adds a touch of warmth and dimensionality that makes them extraordinary.  I had the flagship monos here for a couple months and they are probably my favorite amps in the world.  Tonally they were very similar to my KT88 based Art Audio monos but they also deliver 1100w into any load.  

I am an AVM dealer.  I have no relationship with MSB.
