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.
