A looong while ago I did something I've never done before... I funded a kickstarter campaign for the OSA electronics DACBerry pro :-

Fully HAT compliant Raspberry Pi expansion board with EEPROM support.
The sound seems very good to me, an upgrade from my IQaudio Dac+. Generally the sound seems more effortless, music is more resolved and less confused. I haven't had the chance to listen to it other than on my commute to work; which is a noisy bus journey, so its hard to really get into critical listening.
But already its doing what a proper HiFi upgrade should do, which is give you a new music collection as you hear things you never heard before, even in well known tracks. And question whether further upgrade could take you a level higher; in my case changing my AKG K550 (v1) to something a bit less fatiguing. The treble is exciting, but can be a bit much. Even on my previous dac, I put 4 band parametric Eq to lift the bass and take a couple of Db off the treble.
