The german computer-magazine has compared mp3 to ms-audio.

Comparison of a signal from three sinusoidal curves after
encoding/decoding.

Representation of the interference added before the actual signal. The
upper signal shows mp3 the lower MS audio.

Conclusio:
Hearing comparison between MP3 and MSAudio compressed tones
Impulsive signals become with MSAudio, all the same which tone position, by an
interference
initiated, which reminds of fast swelling. The effect is also in complex material
clearly audibly, best
however in calmer, overtone-poor passages.
This connection accomplished a exzellentes example: The file puls.wav
(http://www.heise.de/ct/99/10/052/puls.wav 344kB)
contains two tones of an
electronic Drum Machine, puls.mp3
(http://www.heise.de/ct/99/10/052/puls.mp3 32kB)
is the result of the MP3-Encoders, puls.asf
(http://www.heise.de/ct/99/10/052/puls.asf 34kB)
the Microsoft counterpart. Who did not install the
new Media Player yet, can hear them as pulsasf.wav.
(http://www.heise.de/ct/99/10/052/pulsasf.wav 394kB)
While Xing and Fraunhofer leave the signal hear-technically practically
unchanged, one can speak with MSAudio actually only of a destruction.
