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!

I was able to audition them with BelCanto integrated amp class D, I Believe. To me it was one of the finest matches Ive ever listen too !
What is that you don't like about the Rega?  Many Harbeth owners think that Rega amps are excellent with Harbeths, and the Aethos is a very well regarded amp.  Harbeth's designer, Alan Shaw, goes so far as to claim that amplifiers with a flat frequency response operating within their power envelope are indistinguishable from one another in blind testing.  I think that the Luxman, the Simaudio, and the Rega are all powerful enough for the Harbeths.  And they are all well designed integrated amps.  Could you let us know what you're looking for from your amp that the Rega isn't giving you?  You'll get more specific recommendations that way.  Cheers!
@smrex13 makes a very fair point

i haven’t heard or had the rega aethos myself but from what i can glean from a quick search, it is a substantial effort on the part of rega to build a very good sounding powerful amp, and it should work quite well with harbeths
I’ve been powering my 30.1 with a Hegel h160, and it works well. Many other Harbeth users are also reportedly happy with Hegel amps.

Having said that, though, as I am now using a (Denafrips) stand-alone DAC, I’ve decided to switch/upgrade to a GATO AMP-150. It is scheduled to be delivered soon, and I’ll give my impressions not long after.
just a sidebar, amusing comment...

alan shaw, owner and main man of harbeth, is adamant that his speakers are quite easy to drive, and any ’decent’ amplifier within the wattage ratings provided per each speaker model will do a fine job

on his user forum, any attempt at discussing better or worse amplification for his speakers are shut down by him with an iron fist, as he personally moderates the discussion forum -- with the rationale that the user forum is about users discussing how great his speakers are, but one had better not try to distinguish a better or worse amp to use in driving them - he doesn't want amplifier brands discussed, yamaha vs rega vs denon vs quad vs sugden.... - it needs to be about harbeth

so ok, alan shaw is completely and totally ’agnostic’ about what amps should be used to drive his speakers (all do just a fabulous job) -- then you ask, so alan, in the company, the workshop, the lab, testing room, audio shows, what amp do you use to test and voice and demonstrate your harbeths?

his answer - ’a hegel h360 for many years, and now, a hegel h390’...

ROFLMAO...
