Just wanted to throw in my 2 cents here... I received my 1909 from J&R on Friday, hooked it up that evening and spent the weekend experimenting with it.
My setup is pretty standard fare, Samsung LN46A550 TV, PS3, Scientific Atlanta HD cable box/DVR and an AppleTV. Setting everything up was pretty straightforward, no major issues. Yesterday I received the XM mini-tuner/dock I purchased on eBay, getting that up and running was a snap.
I was impressed initially, but after running the Audyssey setup I was blown away. I could not be more pleased with this AVR. I'm not an expert and can't offer any comparisons to other models, but I love it so far, and there are still a lot of features I haven't had a chance to fiddle with yet.
I've seen some complaints about the remote, and while it's a long way from ideal it's not as bad as I feared. Although if I had to worry about a wife or someone else learning how to use it, I wouldn't even attempt it. That said, I am definitely anxious for Logitech to update their database with the 1909 codes so I can update my remote (Harmony 550).
