Thanks for the comparision...
I too feel something is lacking at times in the Denon. It is clean , clear and powerful and I was able to get closer to a punchier sound with a subwoofer. Some of the songs sound wonderful and then some not so much. At home everyone loves it because of the AV convenience and the HEOS app and considering the deal I got from Hifimart for the Denon I should really not be complaining. But every couple of months I find myself looking at options once again.
I do feel the one aspect it lacks is the phono stage. My PM 6006 sounded much better with vinyl. I finally ended up getting a vintage Pioneer amp for Vinyl.
Buy the Marantz PM7000N when you can. Its just simply wonderful.
