Mp3's squash the dynamics, frequencies and change the tone of the original track!

Quote- (The mp3 process)
-"Discards or reduces components less audible (ultra low bass) to human hearing
and records the remaining information in an efficient manor"!
"Is not considered High Fidelity by audiophiles"

As an artist, I strive to make music full of dynamics, full of ultra lows and sparkling highs.
Although the Mp3 file sounds better than the old cassette, it lacks the dynamics and frequencies of a C.D.
