But, would they make any difference in the sound from my speakers?

The very high priced receivers typically drive a lot of channels - 11.2 or so - for full Dolby Atmos. They also include a lot of room correction processing, connectivity for lots of inputs, support for multiple video outputs, RS-232 control, and other esoteric things that most people don't need.
But, different receivers do sound different. Their amplifier and processing sections have differences that you might find "better" or "worse". The Pioneer Elite series is pretty decent brand so if it sounds fine to you, and you aren't missing any features (like streaming services such a Spotify) then stay with what makes you happy.
I currently have a Harman/Kardon receiver from the early 2000s. It doesn't have HDMI inputs. But it has good amplifiers, drives my speakers fine, and has Dolby Digital. I plan to replace it with a receiver with HDMI support and more bells & whistles very soon.
