Luxman l-509u or Accuphase E 450

Luxman has a more lively, dynamic, upbeat sound

Accuphase is more of the refine, smooth,wide, deep soundstage type of sound.

Both amps sounds very good in their own ways.

Its more like comparing a BMW vs Mercedes.

I've owned both brands & I could live with either one. There is no bad choices on these amps.

just to throw another into the mix, someone is selling a Jeff Rowland Model 7 amps & Coherence pre-amp which seem to have good reviews , or is it getting to old??

The Accuphase E450 is killer, but I have to add that a mac with autoformers with classic tannoys is infinity listenable.

A friend has the Luxman you are considering and it sounds nice--warm, spacious and deep soundstage, runs cool. I am not sure I'd consider it as the last word in dynamics however. Tell us about your room, source, specs on your speakers, other information is helpful.
