I remember what got me on H-Fi. After being a Shure IEM man for 3-4 years and finally having another cable disintegrate I decided to check out the competition. Hit up CES and heard the ER4 at the Etymotic booth for the first time. Realized a whole other world existed beyond Shure. I think it was the year after the HD800 was released, there was still buzz about it on the floor. I was the Anti-Senn at the time and firmly in the Sony camp w/ my old beater CD2K. Prior I spent most of my time focused on Car audio w/ Alpine, Pioneer Premier, Polk, Focal, Diamond Audio, Phoenix Gold, MB Quart, Eclipse.
