Audio Research Ref75 se

I’m still waiting to hear the amps

but another 2 joined for the race. It is the Ayre ax7. And the Ayre Vx-5 twenty With the KX-5 pre

ANYTHING ARC is probably better than anything else, with caveats, of course.  No company is perfect.  This one is a true GEM.  An ARC pre-amp would complete your system with the highest quality products available.  As you know, ARC pre-amps are, and have always been, considered the best of the best.

As for your speakers, I have no idea what those boxes sound like, but maybe in the future you can purchase some Magnepan speakers and then you will actually be listening to what was recorded on your source info.

Get the ARC amp and never look back.

Cheers!

Oh yes, don’t give it a second thought. I have my McIntosh MC30s driving Sonus Faber Venere S’s which recommend a 40watt min..  I have no problems, let your ears be the judge. 

Have you looked at the Luxman 509X.  This supplies Class for part of it's output so it won't overheat.  I think this would produce plenty of power.  Be curious what others in this group think.

Have been listening to Vandersteens for over 30 years starting with 2ci's to 2ce's and now Quatro CT's with numerous front end brands along the way. In my own system and in many dealer demos I've found ARC tend to be very synergistic and bring out the best in Vandersteen speakers. Agree w/others above should be more than enough power presumably you're listening at moderate sound levels (otherwise 2ce's would not be a good choice).

But as others have noted the ARC REF75SE may be more amp than required for the 2ce's. Personally I'd say that if you plan on staying with the 2ce's long term, you might be better off with SS amp and perhaps using tubes just in the preamp stage.

On the other hand, if you like the Vandersteen's sound and considering trading up to Treo or Quatros (which are both quite a step up IMO) in the not too distant future, then the REF75SE would be a more justifiable investment. 

Pay close attention to reminder about need for balanced XLR's and be willing to familiarize yourself with tube gear which requires more maintenance than SS. If you're going for tubes ARC is a wise investment, probably more so than some other tube brands mentioned above which can be more, let's say finicky.

Good luck
