There are separate quality settings for streaming vs downloading, and you can set it per device, would those fix the issue?

I’ve noticed that the caching will always choose the highest quality available, so I can’t easily flip back and forth between qualities to compare and give you a “big difference” answer. I am definitely noticing more in the low end – bass guitar/cello/kicks are all much more present in the mix. But I can do without that when I’m listening on my phone while out and about. At home with unlimited streaming its no problem.
