Amp recommendations for Hifiman HE1000 V2

I am looking for some recommendations regarding an AMP to pair with the HE1000 V2. I tend to lean slightly to a neutral, warm presentation. I know folks love the Liquid Platinum and Topping A90 for the Arya. Not sure if these translate well to the HE1000 V2.

Thanks everyone.
I have the Hifiman HE400S so am somewhat familiar with the house sound, and if I’m you I’d be looking hard at the Singxer SA-1 amp. At only $599 it’s a fully balanced, Class-A design with plenty of power and exhibits the sound qualities you’re looking for, and you’d probably need to spend quite a bit more to get something significantly better. I believe your ‘phones come with balanced connectors so you’ll get the full benefits of the balanced design right out of the box.  Hope this helps, and best of luck.
Fantastic headphone, you will need a powerful amp to drive them to their full potential. An amp around 6 watts will get the job done, I use a Schiit lyr 2 a 6 watt tube hybrid to drive my power hungry HE560's a great combination. 

Good luck in your search..

Hifiman made an amp that will work great with your headphones.  The EF-6 has 5 watts of class A power.  It's been discontinued, but if you look around you might be able to find one.
Didn't see a response as to budget, but since you spent on the  Hi Fi man phones, I expect you will want a comparable amp.
Also would help to know which DAC you are using.
But regardless, I would recommend the Linear Tube Audio MicroZotl.
It is an exquisite sounding piece & fits your sound profile.

Joyful blessings,

I use the HeadAmp GSX Mk2 to drive my HE1000 V1.

As @pastorbob points out, the DAC fronting your amp/pre will be critical to overall synergy, balance, etc.
Are you considering running your 1000 V2 direct from the Lumin X1's XLR / RCA outs?
Got it. The Lumin X1 is widely reviewed which will allow for a feel of it’s "sound / personality." I’d look to pair it with an amp based on your preferences and goals which in turn is driven by where the HE1000 V2 falls for you and what you want to achieve as an endpoint.

The X1, in my opinion, is a terrific front end for your build.
OP, my favorite amp so far with those phones has been a Yamamoto HA-03 headphone amp, rated at 1.4 watts and it drives them beautifully, the amp I run most the time is the Moon Audio Dragon/Dennise Had Inspire, also rated at around 1.5 watts. The Hifiman 1000v2s are gorgeous sounding headphones with everything I have tried them with but really do get sweet when matched well. I have settled with the HEV1000v2s as one of three sets of phones I am going to be living with and would like to get other peoples opinions of after market cables, so far I have settled on the Moon Audio Silver Dragons to be my favorites and do very well with both my Audeze LCD2s and LCD3s as well. What say you? enjoy the music
The Topping A90 is neutral but has a touch of warmth. It's a fantastic amp. Any headphone can perceivably benefit from amplification. (Regardless of impedance)

Absolutely loving my Pass Labs HPA-1 with my Arya and Silver Dragon cable.
I know you were asking about the other headphones but I'm just giving my 2 cents.
