Integrated amp recommendations for harbeth 30.2 XD


Hi - I'm currently using a Rega Aethos integrated amp with my 30.2 XD speakers.  I'd appreciate your comments / recommendation for a better integrated amp.  Some friends suggest that I consider the Luxman 509II or a Moon integrated.   
Your comments are very welcome!

@pingpong I would imagine the Bryston sounds great.  I had a Bryston B100 with the C7es3s, and it was the best amp tried with them.
To correct myself long after the fact Rega Osiris not Isis their CD player. ;)
@voodoochillin -- keep in mind that both Luxman and Pass are known to understate their specs. The Luxman 590 AXII has been measured to be around 90 watts @ 8 ohms, which is significantly higher than the stated 30 watts. Also, Harbeths like current ... probably more so than watts.
Oh for sure. I’m just really curious how an amp with a really stout power supply which is necessary for a large class A envelope (but low-ish relative watts) drives these speakers so well. I don’t listen loud enough to get even close to the limits of the amp.
