hello, i'v found here positive feedback for Fischer Audio DBA-02 mkII and Yamaha EPH-100 headphones and want to interest few things about them. its 133$ for Yamaha and 166$ for Fischer Audio here (including shipping). should i prefer Fischer Audio for that price? (its nearly impossible to find something with right prices here aka not overpriced) that DBA-02 mkII does cable noise if it worn cable-down and that cable can become hard on cold, right? there are nothing else wrong with them? will that headphones require additional amplifer? (maybe recommended to use with?) i will use it with cowon c2.
