Vinyl sounds better than CD or FLAC; CD and FLAC are about the same and both are better than MP3.

In practical settings, Bluetooth fucks them all up as do ear buds and crap EQ, headphones or speakers. The better your medium format, the more it has to lose from crappy phones/speakers.

Vinyl through quality speakers/phones is still the best I've heard. That said, personally I just use MP3, lol. It's convenient and I can't afford the gear I've heard that really impressed. Anyway, I listen to metal and punk, so it's all noise anyway...
