Having the MA6600 I must say I really love it. Both the Luxman and Accuphase were on my short list. But could not find a dealer to audition them. After a certain level in my experience I have yet to come across anything that "smoked" anything near the level of McIntosh. More a question of shades and flavors. So that Luxman must really really be special. Please post your results should you get a chance to compare both.
