ja_zz - there is 0% potential to go wrong, besides I offer 30-day money-back, less shipping. It’s a small risk to try it at least. Read these customer feedbacks in the last 3 weeks:

Synchro-Mesh will be a much bigger upgrade than buying a new server, even an expensive one. Cheaper too.
Why don’t you try both a new server and the Synchro-Mesh on your Sonos and send back the one that is less good?
At a minimum, I recommend upgrading your S/PDIF cable to my Standard BNC (with RCA adapters) or the Reference BNC (with RCA adapters). My customers tell me it's a no-brainer.
