I just bought a Sonos Connect (July 14, 2019) to connect to my Marantz SR6011 Receiver. It works fine from a functional perspective. However, the sound quality is not very good. It lacks the richness and quality that I would expect. I'm using high quality and expensive Bowers and Wilkens speakers so it has nothing to do with my system. I used optical output from the Sonos Connect and attached it to the TV/Audio optical input of the receiver. There's a CD optical input on the receiver as well, but I would imagine there's no difference in quality. I updated the SW on the Sonos.
Please provide any advice or is this the best that Sonos could do?
Thank you in advance for any guidance or words of wisdom.
