This discovery clarifies a lot of things, including why my new Aiwa CDC-MP3 in my car sounds so much better than what I'm used to hearing on a PC. Winamp's MP3 decoder just ain't up to snuff.
Now, I have no intention of putting up with MS's Media Player interface for any length of time, but I'm not sure which other MP3 players are worthy of attention. I'm trying out Sonique right now, and it already sounds better than Winamp to my ear. But maybe there are some newer or better options out there. Anyone have any suggestions?
