Yeaaaah, no. I looked at the upgrade path this morning, as my trusty Sonos Connect is on the chopping block. The Sonos Connect patches Sonos into a receiver so a traditional stereo system can be used for Sonos output. It can also stream other input devices on your stereo (CD, turntable, etc..) to other Sonos speakers on the network. I never use that aspect of it as I only have a receiver. It's quite handy, has been working without a hitch for almost a decade, and I didn't pay all that much for it. Sonos' suggestion for an upgrade if I turn my Connect in was the Sonos Amp. All the Sonos Amp does is patch Sonos into a receiver so a traditional stereo system can be used for Sonos output. It can also stream other input devices on your stereo (CD, turntable, etc..) to other Sonos speakers on the network. The comparison between the Amp and the Connect that Sonos themselves shows on their recycle/upgrade pages shows that the Amp and the Connect are essentially the same device.
Sonos wants $650 for the Amp. I think I paid less than a third of that for the Connect. Sonos is willing to give me $150 off of a an Amp if I recycle my Connect. Yep..They're willing to offer me the low low price of FIVE HUNDRED DOLLARS to replace one device with something that is, for all intents and purposes AN IDENTICAL DEVICE, but costs 3x as much. And Sonos does not provide any guarantee for how long this stupidly expensive replacement device will last before they decide to kill it, too. This situation Sonos is creating isn't about processing power and RAM, it's about Sonos losing marketshare and forcing overpriced "upgrades" in order to increase revenue.
The only two Sonos Devices I have are the Connect and a Play:3 speaker. Soon, I think, my house will become Sonos free.
