They are comparable in price. Are they comparable in performance (not necessarily sound signature)? I listen to all kinds of music and simply want the most accurate phones -- I can always micro-tune the phones to suit my musical taste, but if the drivers are not capable of producing all the details and frequencies, there is not much I can do later on. I also have high level modding skills with electronics, but I don't intend to build or buy another amp in the near future -- I simply plan to mod the existing amp. What's your opinion?
