I started getting into this whole audiophile thingy. I first got a AKG 6XX and a shiit fulla 2 then i got a fidelio x2 ( their both good but different). Hard to explain the sound but it feels much more cleaner and just better for me when i stopped using awful generic headphone. I will soon also be getting a IEM (most likely a Fiio F9 pro for portable use. But after doing some more research I found out that another way to improve my listening experience would also to be getting a higher audio format. Thing is I only use spotify and just a few songs that I like are not available on spotify and I download few songs from soundcloud and others. But my question is right now does FLAC really help? I can't tell if I got the ears to tell the difference. Also where do people get their FLAC audio from and is FLAC audio available for all most artists since I know it won't be available for like smaller and unknown artists? Does all the audiophile 'pros' have their songs on FLAC?
