I have a similar question, I have new nad pre pro setup driving polk audio rti a9 towers, zp90 is main musical source, I have actually been given a nad d1050 dac to test as I know the rep, luckily, .. Will sonos and it's output limitations affect the final result and as the last user posted, if he had his output converted to 24/96 is this possible if the base file getting to sonos is initially limited by its software?
Sonos to Amp - is simplicity better?
I'm curious if adding a dac and preamp into the path between a Sonos and amp will improve the sound?
