Hi, there.
I own one of these. It had been getting regular use up until 7 months ago when I boxed it and put it in storage for my trip to Taiwan. It is pretty much hassle-free. My biggest issue was having to remember how to make changes when I switched speakers. The two-channel SQ was noticeably improved over my previous Denon 2113ci AVR (piece of junk!).
Now that I think of it, it's going to stay boxed up for another year if our plans come to fruition. Hmm. Hm.
