what about the marantz AV10/Amp 10 combo? Both got outstanding reviews by Gene
Also an excellent choice IMO, especially if you want matching aesthetics. Also great performance.
My AVP is the Yamaha CX, and my amp is the matching Yamaha MX amp. Love the matching aesthetics.
Back when I bought the Denon AVP-A1HDCI, I wanted the matching amp also. Only problem was that the matching amp weighed about 150 pounds. If the amp had weighed 60 LBS, I would have bought it.
But in terms of “hardcore-ness”, I don’t think many amps will be viewed by many to be as “arc-welder-hardcore” as a class-AB ATI amp.
That’s why I let my ATI AT2005 fully-balanced amp power all of my subwoofers and let my Yamaha CX-A5000 amp power all of my speakers.
If I had bought the AV10, I would let the matching AMP10 power all my speakers and still let my ATI amp power all my subs.
Anyway, all of these opinions show that each of us would do things differently. More than one way to do it - for sure.
