Highest rez audio service


So I got a very good highly discerning system and now need music. I really dont want to load all of my cds on a server as i love the ease of sonos in most my home. I know they dont offer high resolution but do any services? Im wanting to use some source into my ps audio pwd/bridge. It just seems a waste to buy cds with so much audio online. Id gladly pay a good amount to have this ability. Thanks in advance.

MOG streams at 320k, which is the highest rez service I know of at this point. Rhapsody is 192k. Both sound very good through a good system.
I read about the MOG being the best bet on cnet. However, will my sonos zp90 let it go up to 320?
Rhapsody, Pandora and MOG use MP3 codecs. Your Sonos will have no problem with these. I really like MOG, but still would love to be able to get Hi-Rez in a streaming format. MP3 is NOT a hi-rez format, even at 320K.
As a matter of convenience, we listen to Pandora One (the subscription version) a fair amount (my wife loves it, and I like hearing new suggested tracks that I didn't know about or forgot about). Pandora One streams at 192kbs. It clearly does not sound as good as my CDs ripped into lossless format or the hi-res tracks I downloaded from HDtracks.com, but it is surprising how good it does sound, and the convenience and price make it a no-brainer to try.
