Wireless via WiFi and Bluetooth works great! It's the Spotify Connect that is problematic.

Based on what you told me, your MediaMonkey use case would be no problem at all. And if you can place it anywhere you want, and turn it up, then I'd say you are good to go!

As for others, if they connect via analog input, Bluetooth or via an app that natively supports DLNA/UpNP, they are good to go as well.
