Received my X3000 today, bought at a price I could not refuse.
I didn't take the time to set up Audassy, but I did hook up the networking speakers and the Wii U (to judge the upscaling).
The sound without Audassy sounded pretty good, except for the relative speaker levels. I will be interested to see what kinds of adjustments it makes. I want to get a better 3-channel sound; while watching a TV show, everything was collapsed to the center (with only a slight sound coming from the mains). Playing with other sources, the soundstage sounded better, but needs more work.
It would appear I have the latest firmware, which is good.
The Denon seemed heavy at first, but when I removed my old receiver, it was much heavier! Yikes. Normally, I associate weight with quality, when it comes to amplification. I hope it has enough power. The Denon has a ton more options when it comes to setting up things, plus with the advanced surround options, so it's still an overall upgrade, but it does make me wonder....
The lack of pre-amp outputs is a bit surprising, but I can probably live without. It's just that I can worry less about the power if I had the option to augment it.
It was hard for me to tell about the video upscaling. Seemed pretty good, but hard to compare? From what I've read, this receiver should do a better upscaling job than most devices. One problem is that most of my other devices already upscale as needed. What I need is a player that will play DVDs at their native resolution, but Bluray players typically upscale, and I want them to play full 1080! Hmm. A dilemma.
