Hi guys,

I accidentally came across the tube amps from Reisong.

Since better from this manufacturer apparently no headphone amps,
I searched a little bit for modifications that allow the connection of a 32 Ohm headphone.
I came across this circuit.

Does anyone here have experience in this area?

It looks like it would work from here. However, this is no different than someone putting a dropping resistor/voltage divider on a vintage receiver or integrated amplifier for headphone use. Your better choice would be to pick something or design something yourself that was optimized for headphone amplification. It's probably less trouble, too, in the long run.
