Whoops! Sorry about that giant image!!! Google Chrome auto zoom strikes again.
It's all digital audio, so the wireless is as good as the local, since it just streams it through its own WiFi network (which has a higher transfer rate than needed for lossless FLAC) and then plays it locally. It's just a stereo output, so nothing multichannel. I would say its very good, but, I hardly have golden ears.... to me they are limited to the file itself.
You don't need a computer, you just need a broadband connection. The sound quality of the Internet radio stuff varies though. Some of it is okay, some of it is bad. It's a database of internet radio stations, so, there is a huge mix. For background music it is great.
Yeah, I have a unamplified zone player and remote in my garage. I use an external amplifier. I've actually never heard their speakers, so, I don't really know..
I have setup an amplified zone player for a friend though, and the amplifier was fine for his bookshelf speakers. It's actually a pretty nice unit... push-down terminals and stuff.
Yeah, your stuck any way you go pretty much. It's nice having a regular digital copy though. I back all my music up to drives. It's a pain but it has come in handy.
No problem!
It is pretty slick. I actually heard about it when it first came out, and kind of shrugged it off. I finally came around. Sonus and AppleTV are my favorite little gadgets now.
I think you can also use your iPhone as a remote, but I'm a Blackberry user so I never tried that. No hacks required, it is just an app.
