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!

The luxman or the large accuphase would be good choices for that speaker they will add a new dimension to the sound over the rega.
I own the Harbeth 30.2 and matched it with the Luxman 590AXII, it's wonderful. Very open and revealing, as has been mentioned already. I will say (in my opinion) they did not sound good with my older McIntosh equipment, and although I like tubes, I felt the high-end  SS amps sounded better with the Harbeth's. I went with the Luxman as it has tone and loudness controls for which I like the flexibility when listening at low levels. If you don't want that feature, several folks recommended Hegel, and other high-end brands which I have heard and are great also a great match.

I have Harbeth 30.1 in the home office and use it with the Raven Audio Blackhawk tube amp. I was generally satisfied with this combo. I also happen to have a Luxman 590 AXII driving SHL5+ in the main system. A few weeks ago I hauled the 30.1s to the media room and hooked them up to the Luxman. Needless to say, it smoked the Blackhawk in every aspect and then some more :)
What is it about the "low powered" SS class A amps that get such great results with Harbeths? I've read very positive feedback about Sugden and Luxman, and with my own experience, the Pass Int-25 delivers amazing realism through Shl5+'s. It would seem then that the blanket statement of Harbeths requiring more power to sound good is misleading. Don't want to start a war here, just my observation.
