I got my 1909 yesterday, and so far, have been pretty pleased with it. I had read about how bad the menu system was, but man, I was still surprised. It took me a few minutes to figure out what the different items meant and did. But I got it set up pretty quickly--I just can't imagine someone new to receivers trying to do the setup.
I have to say that both my wife and I are big fans of the dynamic volume, at least when watching TV. I haven't watched a movie with it yet, but I suspect we won't use DV for that. I asked her last night if she noticed that the commercials hadn't been blaring all night, and she said that until I'd mentioned it, she hadn't really thought about the volume--it was just a nice listening volume. I had to agree. I haven't really put the DV through its paces yet, but it seems that it even does a pretty good job of keeping the volume fairly consistent from channel to channel. I'll have to try to really play with it before I'll know for sure though.
I have noticed some weird things with the sound, where it almost seems like the volume is fluctuating a bit--I don't know whether this was the DV or something else entirely, but it's something I'll have to look into a little more. Either way, it really wasn't objectionable, just something I noticed. I could definitely appreciate the dynamic EQ too, because it seemed like it boosted the bass some when the volume was lower--everything just seemed to sound about the same whether I was listening loud or not. So it seems to work as advertised.
There does seem to be some delay when changing channels and switching inputs. My old Pioneer switched almost instantly, but then again it was doing almost no processing to the signals that came in. The delay is probably just a second or so, but it's something I noticed.
I do have one question for you all though. Under subwoofer setup, it gives me two options, LFE or LFE+Main. Which one do I want? The manual doesn't seem to give any explanation of what they actually mean, but the default is LFE. I have my speakers crossed over, so I want that to play in my subwoofer in addition to the LFE channel, but I don't want my speakers trying to duplicate what the sub is doing. Just wanted to see if anyone knew which setting I needed. Thanks for your help! I'll let you know if I notice anything else of note.
