No. They merely have an excellent reputation. I have never really had an opportunity to audition any headphones over abour $150, as none are sold locally. I will probably have to take a "buy it and try it" approach.
The site linked above has several different brands/models that look inviting, so making a choice could be difficult.
Since I sit about 8'-10' away from my integrated amp, I will need a long cable. Other than that, it sounds like I probably don't need a dedicated amp or other accessories, so maybe I can spend a bit more on the phones themselves.
My one real concern is that I will not be able to enjoy headphone listening, either because of the pressure from the cups (I wear glasses), the noise generated by the cable rubbing on things, or the "inside the head" sound. These are issues I have had with headphones in the past, but of course those were not in the same league as the ones I am considering.
(Note: I currently have a pair of fairly cheap Sennheiser portables. They sound amazingly good for the price, though they are a tad bass-heavy. The on-ear design prevents me from listening for long at a time, though.)
