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
