I currently own a Sonos Connect, that I run through a receiver. I am moving and would like to power two outdoor speakers. Given that I will not have another use for the the Sonos Connect, I am curious whether there are any good options for an amplifier to power the outdoor speakers and pair with the Sonos Connect. I want something that I do not have to manually turn on/off and that is reasonably priced (under $400). Otherwise, I can just buy a Connect AMP.
