SHKong if you decide on the Stax let me refer you to Bob Katz recording engineer who highly recommends an amplifier designed and manufactured in IceLand of all places ,.
Theres a Worldwide following of Birgir Gunjonsson’s amplifier design Mjölnir Audio. Amplifiers for electrostatic and dynamic headphones. I would also like add Birgir is a pleasant man to chat with .
However I don’t think you will find much about it on the main stream sites .
My own interest in using headphones I couldn’t make much sense of of the members of headfi , I stumbled across Katz’s Corner , Bob Katz who knows what the heck he’s talking about and purchased a Mjölnir amplifier, fabulous.
Anyway after less then a year I realized headphones are not for me .
Good luck
