I always have to watch anything on Disney+ on slightly higher volumes than I do anything else, although I don't really notice an issue with the bass on stuff I watch.No, I had to turn up my volume from -17 to -12db to get a perceived same volume as before. But sitting down with a few discs such as Blade Runner 2049 and Tenet, I may be incorrect.
These are both on 4k disc. I guess I am slightly disappointed with the output of Disney + with the bass from Andor where I don't think I had that problem before. I expected more oomph. Is it possible my Sony TV settings for sound got messed up? I will have to rewatch in a bit to see.
But if things go well, I should have a new receiver by mid summer. Looking at the Marantz Cinema 50 for numerous reasons. It has 11 channel processing, it allows you to assign what channels you want to power with you external amp (many only let you do back Atmos - my ATI I want driving my mains), most up to date on video stuff, allows you to shut off power side once external amp is only used, turning it into a pre/pro (hope to get 11 channel Monolith)
Good luck on the new receiver when you get it. So glad I upgraded, if nothing else for the 4K passthrough.
