i hope im not going too far off topic with this post, but the thread title got me intrigued. just for the record ill first state that i did some of my own abx tests, and could not tell the difference between flac and 320 kbps mp3.
thats aside, id like to ask a question. lossless music (may) contain frequencies higher than we are able to hear, however, ive heard theories that very high frequencies that are beyond our human ears can still be perceived as something similar to sound pressure.
also, i have found i have rather treble sensitive ears, and i eq my headphones to make sure ther arent any frequency spikes in the treble area, because i get easily fatigued.
so what do you say? could lossy compressions actually "protect" ones ears from fatiguing (superfluous) high frequencies? could lossy compressions, assuming your like me and you cant differentiate flac from mp3 and such, actually be preferable for your overall listening experience? or am i just over thinking things?
