[LAU] Sound quality with different music players

[bl4]

Hello,

Suppose I have cheap onboard soundcard and cheap speakers, two different 
music players (for example mpd and mplayer) with the same output 
interface (both using alsa or both using oss compatibility layer), no 
resampling, filters or anything, with dmix disabled and no other 
software mixers. Is it normal (or possible) that for the same audio 
files each player will produce noticeably different (in terms of 
quality) sound? In other words, does the choice of music player have any 
impact on final sound quality?
