@chj0 i think stuff like differences between 320kbps vs flac is superfluous unless you are like extremely anal or an archivist. even with my 'quality matters' stuff like orchestral works i dont care that much, and with most music even 320kbps isnt really necessary for most people... most audiophile stuff seems totally psychosomatic to me but if you have a setup with theoretical-astrophysics-experiment level attention to precision at reducing the noise floor and custom-made in-ear monitors or whatever then youd be equipped to notice it better i guess
