I've been looking into the Kingsound after Touch of Modern put them on sale.  I'm put off by the lack of information.  Photos of the amps on the KS website show a blank back with no connections of any kind.  Moon Audio photos do not show the backs of the amps.  Neither site tells you what inputs and outputs there are are on tube amp.  Moon mentions only RCA for the solid state amp.   It's hard to trust a product that thinks such information is of no interest to buyers.

My M-10 has one RCA and one 1/8" input. It has an RCA loop output. I believe the manual is available to the KS website. I purchased the M-10 and the H-03 headphones a few weeks ago and have been enjoying them a lot.
 
Edit: The manual is not available on the website, but KS will email it to you if you ask.

Has anyone tried the H-03 with an other electrostatic amps besides the M-10 and M-20? Any STAX 580V connection should work.

Just ordered a pair of the KS H3 with the M-10 [SS] amplifier.
Was concerned that the M-20 match would entail flabby LF response from the H3.

I was able to audition these on several superior amplifiers with a reference source. How disappointing! Both in sound and construction. A simple pair of Stax SR 207's (with or without the amp) are far superior for much less.

My experience is completely different from yours.
My earlier exposure to the Stax SR-307 left me comparatively unimpressed vis-a-vis the KS H-03.
But tastes and listening preferences have changed for me with respect to other headphones.  I'll try to give the Stax a fresh audition alongside the KS down the road.
