I've heard much better Class D amps than I have Japanese receivers!
May I suggest a Parasound P7 multi-channel pre-amp with your choice of amplifiers is a better option for you then?
I use a P7 with an Oppo 103. The downside of this approach is you are really limited in HDMI inputs, one in the front, one in the back. One option, but it's fussy, is to use the Audio Return Channel (ARC) which is now common. I find on my Samsung TV it is fussy and doesn't always connect, sometimes requiring a couple of power-cycles.
Best,
Erik
