Integrated amp recommendations for harbeth 30.2 XD

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.

I currently have Harbeth 30.2 Anniversary Edition speakers and am using a Bryston B135 cubed integrated amplifier!  It's a perfect match and sounds awesome!  I highly recommend it!  

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.  

I have Classe' CAM 200's driving my Harbeth 40.1's....very transparent

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....
