If I have a record player plugged into a decent amp then into the Connect do I get a better sound quality than if I plugged the record player straight into the Connect. Or does the amp built into the sonos speaker take priority over whatever is plugged into it. ie if I had a super duper amp would it be a waste plugging that into the connect or should I just get a cheapo amp. I will also drive a cd player and airport express and an arcam miniblink for bluetooth through the amp into the Connect. Is there a cap at which it makes no difference what kind of amp you have running all those bits through as the Sonos PLay 5 amp will max out and only play sound quality of a certain level.
