All electrical kit fails eventually, depending on how it’s used and the quality of manufacture and components.

I don’t see where the idea of a conspiracy theory comes in….

I see you've had Sonos almost as long as I have. 2010. All I can say is that it is so frustrating when the components that don't support new features suddenly fail for no apparent reason. And so expensive to replace. I wasted a day of my life trying to reconnect. With help from the Sonos team. Which has gone awfully quiet as was unable to resolve issue even with diagnostic report. £600 to replace the amp.

I get that you’re upset, and your fully entitled to be. But you lost me and most people who’d be inclined to help when you come up with conspiracy theory bs. 

I see that you’re in the UK…. My Play 5 Gen 1 went wrong on Xmas day - the midrange on both channels disappeared completely. I refuse to pay 70% of the new price (which is more than I actually paid for the device) for a replacement, so sent it to https://sonosrepair.co.uk - They are an independent repairer who will try and fix it. You need to pay £19 for return shipping and then their repair costs, which vary depending according to what’s wrong. My Play 5 cost £90 to repair, making a total cost on £109 all in.  So instead of junking/’recycling’ it, it’s playing as I write. I can’t recommend them enough - and have no connection with them other than as a satisfied customer.

Thank you for the tip I'll take it on board.
