I kinda miss the sound of the yamaha receiver now that i get to jammin some of my fav tunes. I have the older rx-v800 35lbs, solid built a lot like the newer 1600/1800, but older and only 5.1, which is fine for me. I like the headroom and dynamics of the NAD, but the yamaha sounded a bit better at higher volumes, maybe my tweeters can't hang..... i think thats it, but the yammi is a bit smoother sounding on quiet passages, but however, the NAD is way better sounding at low volume levels, i guess because of the dynamic headroom. I am running 4 acoustic research performance series monitors, with 1" tweets, 3" fancy material midrange driver, and a nice high excursion 8" bass driver with rear ports. Sound good where I sit, but I'm not yet convinced the NAD isn't getting kicked out of my system, just need to do more critical listening, BTW all of this is running through "good" cables. We won't mention names, cause that aint how I roll, but they are damn good cables and DO make a diff. in the sound and dynamic capabilities of MY system. It's all subjective anyways! lol
