The Best Audiophile Earphones headphones and Amp


I do not own a set of earphones (headphones). I have a high end HiFi system and I am interested in possibly adding a high end headphone/headphone amp.

I am looking for advice/information. What is the best audiophile ear (headphone) and dedicated headphone amp on the market today?

I have heard Stax electrostatics are good.

Check out head-fi.org for all things headphones. I would also suggest that if you are really going for something high end, where you be spending $2-3K, it would be worthwhile to go to a "meet" or to a show like RMAF where there is a major headphone presence. In addition to the many flavors of sound, comfort is something that cannot be determined based on some else's recommendation and is critical w cans.
One thing you should consider is whether you require sealed phones or not. Many phones, such as Grado, are "open" and you can hear every sound in the room while you're listening. The makers of such designs feel that this gives the best sound, but you may require a closed phone for whatever reason. Other than that, there are many good phones out there, especially once you get into the $500+ range. The other thing to consider is - you just may not like listening to headphones as opposed to speakers. I own what I would consider to be one of the top models, but I still prefer my speakers. Still, they're good to have and I don't regret the purchase.
Second headfi site, it is an exceptional resource, like Agon. Everything swampwalker said is accurate and great information.

Headphones and amps are even more pesronal, IMO, that regular systems. Use Headfi and find somebody close to you and visit them and check out their set-ups, it can be very educational and helpful.
I may be the odd one but I think more than 50% members on headfi are teenagers or young adults. In fact I noticed some are as young as 15 years old.
