mulitple surrounds
Given the hype of the Nakamichi Dragon 11.4.6 system, it would be amazing to see Sonos support multiple era 300 surrounds. Adding two more 300s to a large space would yield 11.2.6 which I think would be a good option and in a large room suppprt a better atmos experience overall. Bonus points for allowing the use of more than 2 subs. But I can’t see many users doing that.
