I dunno, it just interests me what others' takes on this are. Do most people like different headphones for different genres, or is it different activities and/or environments? Do you decide that this week shall be AD900X week and next week will be X1 week? Conversely, what would make you be unwilling to listen to a particular pair when you otherwise are willing to give time to your entire harem of headphones?
I normally go after headphones that compliment each other rather then try and take over for them. The TDK ST750 & the Philip L1 for example. The ST750's seem to be bright. They're placing a lot more emphasis on the Mids and Highs. The Philip L1's are a darker headphone and they have great bass impact. One thing that tends to be consistent with my choices are sound stage. I like a larger sound stages. The ST750 has one of the best sound stages I've heard for a closed headphone... (probably due to the leaking) and the Philip L1's are semi open. Sometimes I like to cover the ventilation on the L1's to give it a more intimate sound.
When I'm listening to classical I probably won't be grabbing the L1's but instead the ST750's or even a pair of my IEM. When it comes to IEMs I just love how one single detail, no matter how small, can change the sound completely. My Vsonic VSD1's are a dark warm headphone, while my Gratitude's are a brighter warm. The IM70's are right smack in the middle of both of them and highly likely to put them out of commission. It has such nice... well... everything. When it comes to IEMs I tend to like the mid foward, lean bass kind-of sound. The VSD1's work extremely well with songs that are more laid back and need a little more width. The Gratitude's remind me of an old Jukebox and sound best with swing and high energy jazz. The IM70's just blow everything I throw at it out of the water. Though my testing is still limited to peaks here and there while my fiancee isn't looking.
On that note; I tried out the ST750's built in amplifier and I have to say, without a doubt, I am extremely impressed with it. I normally hate battery functions on gimmick phones, but the amplifier isn't anything like the Beat's or Denon (IIRC) amps. It doesn't just boost the bass to an absurd degree. In fact it functions pretty much like a normal amp would. If anything I think the headphones are lacking in bass. They're very mid-centric and offer an absurd level of clarity.
