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.
