FLAC
using an Asus Xonar D2X with Audio Technica ATH-AD900's
True style. That's what it's all about
WAV for me.
I have the space for my music to be in WAV, Mp MP3 player supports WAV, so why not ? My soundcard and speakers benefit from it, too.
I guess FLAC would be fine, but that's more effort to convert etc.
