Is there any amplifier other than Stax' own to run Stax SR-L300?

Woo has a couple (unless there's something unusual about the pin layout)

I would suggest the Hifiman amp that they sell along the Jade 2.

Nothing special, other than that it's Stax's own six pin plug. Thanks for the good suggestion, but unfortunately none of those in your suggestion have this type of plug.

It wouldn't hurt to contact the guys at Woo, they might be able to do something.
That Woo Wee looks like it works the same as my old Stax Energizer box for my equally old Sigmas.
You'll get out of it exactly what you put into it.

There are various Stax amp options at different price points (lower price as go down the page):
