On my side, I've just sold my Luxman L-505u to go higher in the range of Luxman class A.
I you are a vinyl lover, the phono stage of the Luxman is excellent and will accomode both MM and MC. Plus, the tone control buttons are precise.
It is incredible the reserve of power I had with my L-505u. I never past the 9 o'clock on the volume knob even for high volume listening. The sound of the amplifier is natural, coherent, massive and dynamic. Bass are sublime.
I also heard a L-509u at Montreal's last SSI. I found the same characteristics as the family with a better sense of refinement.
