I agree with wspohn. Due to the mediocre CODAC and the associated high jitter clocks within Sonos Connect, it falls short on most audiophiles expectations. You must use an outboard DAC or get an upgrade by Wyrd 4 Sound.

However I must say, there is no other streaming system I have heard sounds as amazing as Sonos if you are using their own proprietary smart speaker system.
