chesseroo,

I haven't had any stability problems with recent versions of Winamp, but then again I'm using 3rd party input and output plugins, so Winamp is really just a shell (I'm not using it's built-in playback capabilities). In addition to the MAD input plugin for MP3's, I also use the CDReader plugin for audio CD's and the Directsound output with SSRC plugin, which allows me to upsample to 96khz. The end-result is a pure digital 24/96 signal straight to my pre/pro, which sounds fantastic. MP3's encoded by lame at 320k sound totally transparent; I've tried distinguishing them from the original in ABX blind testing and was unable to.

I also use the AlbumList plugin to manage my MP3 collection, and for full-screen visualization I use MilkDrop, which looks truly awesome on a 55" HDTV.
