Hello, idk if this is the appropriate place for this but idk where else to put this, but is the upgrade worth it between these two horns? This is mostly a for the future question as I'm perfectly fine with the 832, it's a wonderful horn and arguably as good as or better than a lot of the more expensive horns out there.

It depends if you'd like to play a 6/4 horn or not. They are very different horns. Many successful players feel a 6/4 is needed, however many have won auditions on 5/4-6/4 horns.

I would not call it an upgrade. More like upsize.

I tried an 836 in a shop, right out of the box. Frankly, I wouldn't have considered that particular tuba an 'upgrade' over many other tubas. If you're 'perfectly fine' with your 832, then I don't see the point unless you feel you have a problem with projection.
