Amp recommendations for Hifiman HE1000 V2

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,
P.B.  

I appreciate all the feedback. I’ll take a look at that P.B. recommended. 

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.

I was think about the aluminum X1 as my streamer/DAC. Any thoughts on this pairing?
