Creative Labs Sound Blaster MP3+ External USB http://www.2buystore.com/shopdisplay...16&Ref=GRABBER

It says it has built-in noise removal, I am running out of options (to help improve the sound quality - eliminate noise) and I have pretty much narrowed it down to the integrated sound coming from the motherboard (it's a syntax 635MP)
