I've got an early 1990s hifi setup with tuner, CD, tape deck and amplifier that I would like to use to play my digital music collection. The amp has a spare aux input with RCA connectors.
I think I either need something with a USB input that has a decent display and controls to navigate through the folder structure or a bluetooth/wireless solution that I can control from my phone.
Has anyone done something similar, and did it work out well?
