Trying to find a music server that has on-screen video display feature. You know, like an AppleTV, but not a POS.

Something that can be integrated into a Home Theater system remote control for conventional control features.
I no longer like the concept of having an iPad to control the music.

Tried the Autonomics MMS 2A, but was not very impressed with it's abiltiy to function, in general.

The Linn products are a bit (way) out of my price range. 

What else is there ?
As far as I know, the Pi products do not support any third party control systems like RTI, Elan, Savant, etc, which is a requirement for my application.  If they had control / transport drivers or Rs232 strings that worked with any of the above, I would love to try it. 

Fwiw, I have an Oppo 203 in a HT system.  The Oppo recognizes my NAS, so I can stream from that.  I have an Apple TV in the system and yes, it is a POS in general, but for Internet Radio it’s no worse than the Bluesound Node2 in the same system, which I use for Qobuz.  That is a lot of boxes, I know, and of course if you buy an Oppo you will have to pay extortionate prices.
   I never intended to use the Oppo to stream music files, in fact I was surprised when I learned it had that capability, but the advantage of using the Oppo over Bluesound is that I know it will actually work every time I want to listen, whereas Bluesound tends to crap out for a while after each mandatory software update (and they  are frequent, as they constantly have issue new ones to fix something broken by the previous).  And my main reason for the ATV is that I don’t have a cable or satellite provider, and again due to Bluesound issues it is a more reliable provider of Internet Radio.
