I picked up a 1016 about 6-8 weeks ago after a about 3 months of research and reading and listening. I didn't want to post a review right away. I wanted to live with it for a bit, and get my new speakers. I can now say this amp is exceptional. I'm extremely happy with it. In fact, I just convinced a friend to buy one. The setup is easy, and the auto-cal is unbelievably accurate, I only tweaked a few tiny things.
One of my favorite features is the ability to assign inputs (optical 1, optical 2, etc.) dynamically to the various buttons/channels (TV, DVD, VCR1, etc.) This only works for digital inputs, but since that's what most of my setup is these days, that's all I needed. That feature makes life so much easier (rather than trying to remember your DVD is plugged into "sat" because that's the connection you needed and your cable box is plugged into "DVD", etc.).
The main reason this was my top choice was that it had every feature that most $700 amps had. And I was willing to spend more money for the right feature set, but this had it all at under $400! I still wasn't convinced - I wondered what I was missing for that extra moneym but after reading mostly stellar reviews here, and listening to one in a store, I was convinced. I have no complaints about this unit.
For what it's worth, I have this unit setup with Digital HD Cable, a 50" Zenith Plasma, and the Klipsch RF-52 set of speakers. Tied together with the Harmony 880 universal remote, I'm in heaven.
