Marantz Ruby PM KI amp vs Accuphase e-480 or e-380


So... does the Marantz "economies of scale" trump here? Can they make just as good of luxury product for cheaper than the more "boutique" brand? Sound quality -wise, is the Ruby PM KI amp just as good or better (though without the features) as the Accuphase e380 or e480...?

My preference is detailed but perhaps on the warm side of neutral...

Could run either of ’em w a bluesound node going through the Ruby SACD player dac, so consider that the source(s).  Just consider that to be my inputs, into the Ruby and/or Accuphase amps, to control that point.  So the question is about the amps. 

And btw... I know there are plenty of other choices... but let's keep this discussion focused to my question at hand; I've heard all the arguments for all the other possible amps in this world, and I'm down to these two for the purposes of my question; I'm not interested in hearing about a bunch of other brands.

Another related thought, although it would likely void the warranty, if I bought an Accuphase, say the 480, in Japan ... could it be easily "rewired" to be American power (110/120) ? A high end repair shop ought be able to do that for a couple hundred bucks I’d think, or am I mistaken.

I've had 2 REL subs linked to my Ruby's speaker binding posts for a year or so with no issues. Sounds wonderful. 

Also, I have played around with tons of amps on extended basis. This amp is an exceptional performer. It is a reference level piece that can compete and best stuff costing way more. 

Opening the box of the Ruby products is a treat.  The Japanese build quality is something to behold.  I think Ken should have added some bling to the cosmetics because it looks smooth and strong but could use a bit of flair. 

Thanks @jjss49 ! 

I took a summer hiatus from my hifi obsession, listing only once per week--which is rare.  I used the time to hit the woodshed and get my fingerstyle guitar skills back to where they should be. It saved me some component jumping costs! But I'm back.
