Added functionality has always translated to added cost. If you were to get the added features you want,
now how much would you pay?
I agree with Owl's_Warder. The flagship model may have these added features, with more cost.

I like that my current 976 and my previous 975 were in an affordable price range for me. They both did exactly what I needed them to do. Reproduce the video and audio, and they both have great SQ.

I also use the Harmony 700 which I only have to choose an activity and sit back and enjoy. I barely even look at my 976.
