I have a stereo pair setup of Sonos 5s. Using the S1 obviously. When I play apple lossless files I've ripped through itunes some stutter. When played on S2 capable (Beam, etc.) They do not stutter. I have tried separating the pair and it still happens. Any thoughts??

Suspect there’s some issue between the speakers on S1 and your router in terms of wifi interference , but not between your S2 speakers and the router.
There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.
