ARC Ref Preamp with Constellation Audio Centaur Amp

[FlexibleAudio]

I am thinking of matching my Ref 10 with Constellation Audio Centaur Mono amps. I am curious if anyone has tried this combo or maybe the Ref 5SE or Ref 40??? Or, for that matter, any tube preamp experience with the Centaurs would be welcome.

Thanks in advance for feedback,
