High End Headphones And HP Amp.

Today I’m taking a blind leap of faith (no audition) and purchasing a set of Focal Stellia HPs and a NAIM Uniti Atom Headphone Edition headphone amp. The new NAIM Uniti Atom HE amp is getting rave reviews. I need a set of high end closed phones and top notch HP amp. The amp is brand new on the market. I thought I’d take a (long) shot in the dark and see if anyone has heard this HP amp and/or the Stellia phones? Thank you.
No, but really depends on what sound characteristics you’re looking for.  Nice ‘phones, but you really want to pair them with an amp/DAC that compliment them for your tastes.  What are you looking for?  You might be able to get what you’re looking for at a lower price, or get something better for comparable $$$. 
Most people ask first, then purchase. Interesting approach. 

I have the Focal Elex and have heard the Utopia. I don't think you'll regret your headphone purchase. No experience with the Naim amp, but they make good stuff. 

Come back and tell us how you like the combo after you have 40 or so hours on them. 
For the life of me I can NOT understand WTH listeners are hearing with Focal.I demo’d Clear & Utopia,like sticking my head in an aluminum can & listening.
ABSOLUTELY no natural,organic warmth,NO SOUL!NOTHING but a cold,lifeless,mechanical presentation & that was off a HIGHLY regarded tube amp..
As for the Naim,never heard one but VERY pricey considering a few hundred $ more gets you a complete integrated solution that also drives speakers like the Pathos "Classic Remix"or a gently used McIntosh MHA-100/150..
Focal dealer told me to stay away from the Focal brand as he is sick and tired of handling all the warranty work on them. He told me to get the cheaper  Meze Empy instead. I was very happy with them. A warm, comfortable, non-fatiguing headphone. I paired it with the very neutral Benchmark HPA4. However, I sold both of those when I got the RAAL SR1a. Hard to compete with the RAAL.
I tried a lot of headphones and the best for me up to now are the ZMF verite closed. I just ordered an Allnic HPA 5000 xl to upgrade my amp.
Unfortunately for me open headphones are nor an option for me but if it was I would recommend either the Final D8000pro or the Kamerton. For electrostatics Soltanus system.

I have Focal Utopia and ZMF VO's, along with Hifiman Susvara. I love the Utopia and ZMF (I use tube headphone amps - I don't care as much for SS headphone amps), but Susvara is almost in another league altogether. 
I am enjoying Abyss 1266 Phi TC headphones and Niimbus headphone amp with a Danacable Lazuli Nirvana cable between headphones and amp. The combo is nice but very pricey.
