Obviously we have a few uneducated people when it comes to mp3's here. If you download a high bitrate file and you have a high quality soundcard they sound excellent. I use the TOSLINK output on my soundcard and feed it directly to my DAC. If the mp3 file was encoded properly the sound quality should be excellent. It's not as easy as just saying "mp3's suck". a 320 kbit/sec mp3 file is right around a 50% compression of the original. Compared to dvd's, minidisc, etc. this is a very low amount of compression. I've encoded several of my audiophile cd's to mp3's and then played them back side by side with the originals and only a couple of times have I noticed any difference and even then it was enough to leave me doubting whether or not the difference existed.
