I had read that some of the speaker amplifiers treat their headphone jacks as an afterthought which would be disappointing after buying a good set of headphones. Right now my PC uses a creative...

Well my Bose QuietComfort 15's finally bit the dust. I had purchased them a couple of years back to deal with excessive background noise of the room I was to be in. Having since moved all my server equipment to a dedicated soundproofed server room, background noise is now no longer an issue so I...
