I'm in the midst of a major purchase for my audio setup. Just a quick background on my project. The computer will be the entertainment hub and one of the components is an external sound board. I had my eye on the SoundBlaster Extigy which has had some mixed reviews but is still a front runner for me at this point. I just found out Yamaha makes one as well which looks 100 times better but also cost more. I'm reading the review and they say most DVD movies and music are encoded in 16bit so 24bit (which both unit claims competency) is only for people who actually do recording/mixing/etc. Here's what I don't get. My MP3s are 128kbit! and 44khz, but these units are only 24bit max! I know I'm missing the translation somewhere, so what gives ?
