I'm nowhere close to being an expert with computers, but I like to play around to see what happens and some of what I've tried might be useful to someone else out there.
I had beginner's luck with the 3311. I made all the connections before powering it on. When I fired it up and got into the menu the 3311 had already been assigned an IP address and it had already found some media servers on my network.
The first thing that surprised me is that the 3311 found a network hard drive. It's a WD My Book World Edition. The first thing that surprised me is that I hadn't installed any media server software on the drive, and I was unaware that it came with any.
The second thing that surprised me is that my computers usually can't find the network drive until I re-map the stupid thing each time I want to use it, so I was shocked that it worked so smoothly with the Denon.. The 3311 has found the network drive every single time, so I'm just going to load more music onto it and use it as an audio player with the 3311. Instead of cussing at the My Book constantly I'm glad that I've found something it does well.
I've also turned some old computers into linux ubuntu computers that I'm mainly using as audio players. I bought the computers back around 2002. They were good XP computers in their day, but after five years or so of heavy use they eventually reached the point where they didn't even load Windows any more, so I hadn't used them in years.
I downloaded ubuntu and burned it onto three identical CDs. All three of the old computers came right back to life with ubuntu. The installation process couldn't have been easier. I don't think that I would want to switch to linux completely on every computer, but I'm impressed with how stable it's been in those three old computers. I can leave them on for weeks at a time. I don't recall any crashes so far in several months of using ubuntu.
One great thing about the 3311 is that it plays flac and ogg files, which is what the ubuntu CD rippers use. Even though I can usually stand listening to mp3 files, there's absolutely no doubt that flac files sound considerably better. The difference is more noticeable on some songs than others. I also have a Yamaha 3900 receiver, and I like it, but it doesn't play flac and ogg, so I appreciate that ability of the 3311.
Ripping CDs can be a chore, but having the three ubuntu computers side by side makes the chore go a lot faster. Considering that I hadn't used those computers in years I'm glad to give them a productive second life as music servers for the 3311. I can also play the music on those computers from any other location where I have a good internet connection.
I still have a lot to learn about linux, and a lot to learn about the 3311. My only real problem with the 3311 so far is that all of the network music options begin to stutter after a few days until I reset the microprocessor. After each reset the network music options play perfectly for a few more days before they begin to stutter again.
I don't really mind resetting the microprocessor. That's easy enough. The hassle is in having to set up all the options on the 3311 each time. The only good news about it is that I'm learning my way through the menu maze faster than I would otherwise.
