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!

there are several threads on the right amplification to drive harbeths... much has been covered

search and you shall find

short answer is upper tier refined strong solid state:

ayre, hegel, pass, upper luxman, upper naim and some others like primare i-30, sony ta-1es class a, some musical fidelity... and of course some of the megabuck units like gryphon, coda etc etc
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.
