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!

A dealer I trust recently told me he would be happy for a very long time with the 30.2’s paired with a Rogue Cronus Magnum III.  
surprised no one has mentioned Vinnie Rossi L2i SE...I had the Hegel H590 and 40.2 anniversaries in a fairly small room and when I switched to the Rossi I never looked back...pretty amazing combination, IMO. If anything, given the 100W, its a touch light for the 40.2s, but would be ideal for the smaller Harbeths....one issue though---when using the internal DAC on the H590 it sounded better than going with an external DAC, and so the total investment was higher not to mention the pricier Rossi integrated by itself....
@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. ;)
