Mcintosh MA6600 vs Luxman 507u

I use to own a Luxman L-507U.Best Sounding Int amp i have ever owned.But i sold it on Audigon.The person who purchased my Luxman L-507u was running a McIntosh MA6600.She told me the Luxman L-507U SMOKED the McIntosh MA6600.

why did you sell your luxman and can I ask what you sold it for?

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.

I know that many quality amps can sing when they are pushed. At lower volumes, say around 4oclock, did you still hear the same?
