What are the best bang for the buck on higher end headphones?


In the last year, after solidifying my main system I have moved on to establishing my headphone system which is in our home office/game room, as this system has grown I am now at the end of the game and have just pulled the trigger on a Dennis Had Inspire headphone amp from Moon Audio that will replace my Yamamoto HA-3 amp & will sell it as well as the extra headphones that my Hifiman XV2 have beat out, with that said I want to purchase one more set of cans to go with the XV2s and have my mind on the Hifiman HE1000v1, HE1000v2 or the Focal Utopia and have found really good deals on all these mentioned as demos from dealers. I am partial to the Hifiman house sound versus Audeze but is there some cans in this league that I am missing. Have not heard the Utopia but am willing to take a chance at the great price I have been offered. What say you?

@freediver , are the Focals you refer to the Utopia? Have not heard the HE 6 cans but all the reviews seem to love them, they are just hard to drive with a headphone amp as you know. @big_greg, talk to me about the Audeze 4 if you would as I am basing my judgment of Auzeze on the LCD2F which actuslly got me started on this quest a few years ago.
I LOVE my HiFiman Arya. I used to have other headphones including the Focal Clear. As someone said above, I too can understand why people like them. However, they don't have anywhere near the midrange warmth that the planar Aryas do. 
Many people say the Arya is the sweetspot in the lineup. 

That probably doesn't answer your question. I just wanted to contribute a post on the new headphone thread on Audiogon. Lol.
@tooblue The LCD-4 are the best headphones I've ever heard. I haven't listened to all the uber expensive cans out there though.

I own LCD-2 (I think mine are non fazor), LCD-XC, Sony MDR-Z1R, Focal Elex, Sennheiser HD-800 and a few others. I spent some time this morning listening to the LCD-4 and the Sonys and Focals. The LCD-4 are really easy to listen to and provide visceral bass that the others can't with slightly warm but incredibly detailed mids and highs. If you like Steely Dan, Black Cow on The LCD-4s is pure bliss.

The only negatives to the LCD-4 are their weight (really heavy!) and they need a lot of power (and their price). I love the Focals, they are really detailed without being bright. The Sony's are really nice and produce a lot of bass, but it's not as tight as the LCD-4.  If I had to get rid of all my headphones but one set it would probably come down to the Focals and the LCD-4. The LCD-4 win on sound quality, the Focals on comfort. 
I had a couple of different Audeze headphones and they were all like cinder blocks on my head. Love the midrange and bass though! 

The HiFiman Arya has tremendously beautiful midrange, extremely sufficient, tight, low-end bass. They are also the most comfortable headphones I've ever had. And I am a Former hd800 owner.
