Mcintosh MAC7200 or Hegel H390 for a new pair of Kef R7 META

Music source into the receivers is what?  Room size?  Preferred music? 

I'd consider a Unison Research, Unico 150 to pair with the KEF R towers... a departure from the mainstream yes but maybe read the reviews and try and demo one. I bought a 150 for my son & his wife for their new place. He's got Focal, Kanta No. 1 & I have to say, it is an impressive pairing for sure.

@jheppe815 Great advice! I was very close to pulling the trigger on a new pair of Meridian DSP5200Se but decided to go the separate route. Thanks for the breakdown!
