You really need to think. How can a needle in a plastic groove going round and round on a turntable, vibrating a coil in the cartridge, with all the snap, crackles and pops, and rumble, be better than a CD taken from the original master mix, or sampled from a pristine LP via DS-SD converters costing thousands. The range of a CD far exceeds that of a vinyl (yes VINyl not VYnil) LP.
FLACs are noticeably better than mp3s, mainly because mp3s are heavily compressed to keep their size down, but most mp3s are listened to on phones & cheapo headphone/earbuds.
Somewhere on You Tube, also compressed, there is a film of an experiment where the same music was played to the audience via dog's bo11ox sound system, from the master tapes, CDs, flacs and mp3s. Guess which won!
As we age, out high frequency hearing deteriorates, I cannot hear above 11kHz, and blew a tweeter in my Paradigm speakers trying to get more top end. Just got to live with it.
