May I ask, why do you need on-screen volume display?
Just curious
The Marantz 8002 has it, but I usually set volume based on source from front panel and then
adjust by ear 
The setup is on screen which was more important to me. I rarely look at the audio on screen.
I had a Pioneer Elite VSX 45 TX before but had some failures; the video switching went out. And then there was Pi0neer support who told me they did not support Def Tech speakers when I had a power tripping issue: it was a whisker wire short on the center which tripped above low voulme.
Good Luck!
