ARC REF5se and REF75SE, Accuphase E-650, Luxman L-509X

  • Looking for advice/feedback on these three setups, and comments on their pluses and minuses
I am an new owner of the ref 6 and Ref75se.  FWIW, They are still breaking in, but they are magical.  Smooth grainless highs.  Not bright either.  Just natural timbre.  
The Lux L-509x is fab. Bought one last month. I am still breaking it in, but will tell you that right out of the box it was wonderful. Smooth, detailed, big sound stage with no harshness on any level.
