Well, there are certain factors you need to take into consideration:-How good are your speakers/headphones?-How good is your sound card?-How good is your hearing?It may depend on what type of music you listen to too, but i'm not sure about that.
@DzierzanPLYou can't change mp3 to WAV because WAV is a higher quality format. You can retrograde codecs (i.e. FLAC to MP3 or WAV to MP3), but you can't improve the sound from nothing.
