Yamaha A-S3000 Vs Marantz PM-10 (new reference line)

Myself, I would prefer the Yamaha (I've only heard the Yamaha in person). However, I no longer sell class D short. Heck, my early 2000's Pioneer Elite A/V receiver sounded really good. Class D, from what I have read, has come a long way since. 

Noble, you are describing my experience (although limited) with class D. The early 2000's Elite receiver sounded way better than my 70's Pioneer receivers I had back in the day. I'm sure modern class D has improved even since then. 

I know this is irrelevant when it comes to sound, I think the Yamaha will hold it's value longer. I could be wrong, I think Marantz is seen, along with brands like Pioneer, Denon, etc, as more of a general consumer brand. Yamaha has a strong footing in pro audio and instruments. Again, just a perception.
