A couple observations after only a couple days with this receiver:
PROS--This is the best sounding receiver i have heard. i am coming from a $500 mid-line Denon and there is no comparison. The sheer amount of power and detail is night and day between the two. I also briefly had a Yamaha Aventage hooked up (it died rather quickly) and it sounded really great, but not as clear as the NAD with music especially.
It is a very simple unit to setup and operate (assuming all the options work correctly.....will get to that in a second). Simple, very simple menus which I like. I don't need a receiver for 100 different zones, streaming music, etc. I use other components for streaming (Oppo 103) so i like the bare bones approach.
It also runs very cool.I have it enclosed in a cabinet and it barely gets even a little warm, so zero chance of overheating.
it also feels very solidly built.
CONS--the Audyssey setup does not work. Everytime that i try to run it, I get a check type beside all speaker types. The speakers are hooked up correctly, and the test sound waves are played through them, but then it says check type and cannot go further. i will setup manually with an SPL meter, but this is a problem.
Another thing--although the 5 preset sound modes is a nice thing. they sometimes have problems switching. Maybe some of this is user error with it being a new unit, but like i mentioned, setup is pretty elementary and I can't imagine that I'm doing anything wrong here. The dynamic range control similar to Dynamic Vol on Audyssey units does not work at all. I have changed the settings and stored them several different times, but when you switch back ot the preset, it is every bit as loud as normal range. Any advice from other owners would be welcomed.
Lastly, i can't seem to get any bass output from the subwoofer when switching to Directv. The sub is on and crossed over at 80 hz, but there is no output with this unit. This is probably user error.
Anyway, there are some kinks that hopefully i can get ironed out, but this unit is very well built and the sound quality makes up for the small problems for me. Just a beautiful sounding unit.
