Hi Kumaresh Your right when you say that these files sound better in a 5.1 setup.But theoretically a MP3 Surround file's sound quality would be similar to the MP3 surround file when using a good 5.1 decoder.But we find MP3 surround to sound better in a 5.1 setup as the sound comes through 6 speakers and in a 2 channel setup all sounds comes through only 2 speakers,so some sounds get burried in a 2 channel setup.
MP3 and MP3 surround are both compressed or lossy formats.This is because when you encode from a Audio CD (1411kbps WAV format) the mp3 encoder compresses the original file to a lower bitrate specified by you (320,192,128kbps ect).Normal audio CDs sound good because of the high bitrate and the uncompressed format that they use.
