Any Allnic HPA3000 MK1 users out there?

Thinking about pulling the trigger on the newest Headphone amp from Allnic.
The reviews and forum discussions on Allnic are very positive. My system right now consists of a Rega RP3 TT and the Ayre CX7-emp as the sources. My amps are from Heed and my Headphones are the Hifiman HE-500's. Cabling is all Audience. I listen to 70's soft rock and new alternative singer/songwriters mostly.
Any thoughts or comments on this amp or Allnic would be appreciated. Thanks
