The analog output from any of the music server/Sonos/SB3 is a waste of time. I have a fully modified Bolder Sb3 and it does not come close to an external high quality DAC. The key is a very good quality DAC and then you can get rid of your expensive cdp.
I have switched over to music server a year ago and have never looked back.
