The idea of having my speakers and amps go EOL is bad. Speakers and Amps can last 40+ years in the audio world. At this point I have no plans to upgrade my sonos products due to the idea that new products will only have support 5 years after they are discontinued. I understand that tech changes but i should not be forced into this and have my thousands of dollars of equipment just stop working at some point.
I think sonos should come out with a bridge with beefy CPU, ram and storage that can act as a way to continue support for the legacy devices. The bridge could stream music to multiple legacy devices so they do not go obsolete. Please consider this. Its the only way i will ever buy another Sonos product.
