I ordered the AVR-1912 and got it set up last week.
To be honest I wasn't that impressed with the sound out-of-the-box, though the connectivity, setup, and controls on the receiver were great. The highs were harsh, there was very little low end, and the midrange was overpowering. I was starting to wonder if I made a mistake in purchasing this amp.
On Saturday morning, I decided to run the Audyssey autosetup. WOW, the resulting audio quality was an amazing improvement. Over the last 2 days, I can't stop listening. Even the high-quality MP3s (I do -V2 LAME encodes) coming out of my dock are wonderful. The harshness of the highs are absolutely gone, the bass response is now present, and the balance between the mid, low, and high are just right.
It's only been a few days, but so far I am happy with the receiver. Thanks for the recommendation, BllDO!
One of these days I may even set up the receiver in bi-amp mode, which I didn't realize I would be getting with this amp.
