Anyone out there with a NUVO system?

At the time 2014, the NUVO system looked like a good plan for a distributed home audio system. As most things go, it has been rendered obsolete, with the company sold off to Legrand Industries. They no longer support the MPS4 line of products, now using something else. I still use the amplifier system and an Apple TV as a source to stream Spotify, iTunes, etc, but I would like something more integrated. I have a whole bunch of keypads around the house that would be a pain to remove and Sheetrock. Anyone who still has this system have any new upgrades or additional compatible components?
