LPAs is around 3dB louder than LPBs, that's a quite significant difference in loudness, which to now, no-one has commented on. The mp3 code/decode process also hides many of the subtleties in the original audio which we are trying very hard to hear. If the two files were uploaded as uncompressed .WAV files for us to download and compare then there may be a basis for a more legitimate comparison.
LPAs peaks to the digital maximum, which may overload some playback systems, making the vocal sound "hard" akin to tracking distortion.
