Audio stuff

My friend just intro-ed me to some freaking nice and cool audio stuff. Very high end. I've only really researched about Sennheiser, AudioTechnica and Phonak. This friend who studies in UK reminded me of Bose and Bang & Olufsen. I've seen or heard of these 2 brands somewhere sometime ago but could not recall them. But hell now i have the time to research them properly, i begin to crave to have a Bose set at home. Argh. You know what car is outfitted with Bose? Audi R8 dude. R8!
