My IT guy was here this morning. He helped me out with some nagging problems with my machines, but since he also does sound systems for houses I asked him for a solution to my music needs, mainly upstairs.
I have posted about this in the past. He told me that it's simple: A Sonos amp system can do it all. It can feed to my existing speakers (wires), can stream WQXR (Wifi), can handle my CDs (which are important to me), and has portable wifi speakers to move around if I want. He says the rich folk love the sound quality.
I think my ideal is unobtainable. No - my ideal is live music.
