Serious question: What alternative phones do you suggest? I've tried PinePhone and PinePhone Pro and it was painful.
It wouldn't be advised to buy the latest pixel now anyway, either get the previous one or wait a few months for Motorola Signature 27, where GrapheneOS will be first party OS, and not hated-by-the-vendor bolt-on.
If you insist on the latest pixel, go check the GrapheneOS discussion forum for all the details.
Instead I have to buy the shitiest locked full of crapware android phone and hack it with an LLM to make it usable because apparently that's what I deserve for wanting a headphone jack.
Best of both worlds.
The DACs/amps you linked are bigger than the Sony mp3 player I had in 2004. It had two jacks and a user replaceable battery. And it was water resistant.
I could go on and on.
Take care!
