Anyone know much about these?
I use mine strictly as a music server in a two channel system. It is a little quirky sometimes and requires a re-start every now and then, and a wireless re-connect from time to time, but that's easy enough. Aside from that, I absolutely love it! If you want the best sound quality...definately use a DAC. I use a Cambridge Audio DAC Magic, and I noticed a huge difference when I connected it. I do rip cd's as Apple Lossless, but I also buy individual songs on itunes when I only like a few songs from certain artists. I gotta tell ya...there is a difference between Apple Lossless and the 256kbps you get from itunes, BUT it isn't as big as you would think, in fact it is very subtle. I only noticed a difference when doing an A/B comparison with very critical listening. One of my favorite things about it is...you can totally customize your itunes library and it will be the same on your Apple tv. For instance, I went through my whole library(3500 songs) and created my own genre's, playlists, selected my own artwork, album titles and so on. Now...whatever comes up on the screen is what "I" want it say, and how "I" want it to look. Let's say you have five different cd's from the same artist...James Taylor for example. You can select an album cover you like the best for all the songs and change the album name to James Taylor Collection, OR... you can have it as diverse as you want. Anyway, it works for me. I recommend it.
