As someone who has actually has the unit, I can comment on the fact that $1400.00 is an excellent buy for this unit.
1. Is this a new unit?
2. Is it a B-Stock by Integra?
3. Is it the DTR 80.3 Receiver or the DHC-80.3 Pre/Pro?
It is an excellent Pre/Pro, but it definitely is not perfect.
1. I have never been disappointed with both audio & Video
2. I have never had a single issue with mine, it does come with a 3 year warranty if new, 2 year with B stock (non transferable)
3. I am pretty sure it has Dual Sub control, though I am still a poor guy with only one sub
Keep in Mind
1. It does NOT do 4k pass through it only upscales
2. It is not AirPlay Friendly w/o and adapter
IMO if you can wait, as I am doing, I am wanting to see what new receivers come with the HDMI 2.0 Standard as I plan on upgrading to 4k TV and want the extra bandwidth.
Bottom line though at $1400 that is a great buy
