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.

This set-up sound the best to me but my experience with headphones and headphone amps is limited. I'm really enjoying a set of AKG K701 earphones with a Schiit Audio Valhalla tube headphone amp. I know this may be considered budget/entry level but it sounds good to me and I didn't break the bank.
This is the thread that never stops. I always laugh when I see any mention of Schiit Audio. Like so many products, it probably has a signature sound. So...what do people say when they hear it? "WOW! This sounds like Schiit."
I have used Stax phones for decades now. I had the Stax O2 mk1 and mk2 and other lambdas. I actually decided to keep the Stax Sigma Pros (very rare) and a pair of Lambda Limited edition (very good). Both are confortable. I plan to acquire the SR-009. My amp is the Stax SRM-007II. We are talking about a $ 3000 setup here which is reasonable.
If anyone is looking for great audiophile headphones (at any price), I really love and recommend the Audeze LCD-2 Rev 2 (that's the current version, this Revision 2). I've had LOTS of phones and these really seem like the top ones to me now. Here are my comments after getting this new version of the LCD2s.:

Well, way to go Audeze! I finally broke down and got the Rev2s, and they are much better than the originals and are fantastic phones, period, just with their stock cable with a conventional 1/4-inch plug.

(1) They have no sluryness or sense of overhang that I find orthos can suffer from (including HE6s).

(2) They do not ring at all in the upper midrange, so important to non-fatiguing vocals.

(3) The bass is controlled and detailed.

(4) They have great definition without any hyped up highs. I always thought conventional dynamic phones were needed for this level of definition, but the Rev2s are right up there with Beyer T1s, Senn. HD800s, and Denon D7000s in this area.

(5) They are excellent with my tube and solid state amps (but the tubes give more saturation of tones, a more continuous sound; but even with tubes, the bass is not soft and is quick and satisfying).

(6) The highs are (Goldilocks-like) "just right" to me (a rare achievement with headphones).

(7) They are just plain balanced over the entire frequency spectrum, more than any phones I've tried (& I've tried many of them). No anomalies that I can detect in the Rev2s.

Just plain shocked at how good these are out of the box. A big step up for me over the Rev1s.
