Koss head amp /E.9B driving Stax headphones

[powwowme]

Dear fellows,

Maybe you can help me with an advice. A friend of mine gave me a Koss head amp E/9B but without the suited headphone. I want to know whether it is possible to play a Stax headphone (normal or Pro Version) through this head amp. If it does not work - it is possible to convert the Koss working with a Stax headphone, maybe by building an adapter?

Many thanks in advance.

I wish you a great happy new year 2018.

Best,

Andreas

No would be the short answer.  The pinout is different, the transformer setup is different and the bias supply is very different. 

Now you could rip everything out and do something like that but it would be a lot of work.
