I don't want to use my phone because 1) it will use quite a bit of battery and 2) I only have 128GB non-expandable storage on the Pixel 3. All of the FLACs I have would eat through that storage. I probably should have put that in the OP, my apologies!
FiiO M7 maybe? Reviews from its release are positive and it's down to $130 on Amazon. I may have answered my own question haha.
It's your potato my man, fiio makes nice stuff, I've been happy with everything I own from them.
