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
