risquare Big 6 Communications Software Plugin for HS4

I haven't used all of the features, but it works perfectly for my use case - controlling a Marantz AV Receiver. Marantz and Denon receivers can be controlled over a Telnet interface over TCP. I needed to set up two Telnet profiles in the Big6 plugin: one on port 23 to control the physical device (on/off/input...) and one on port 1255 to manage the streaming content (playlists). Very satisfied.
