I don't know since it's a small company which produces it. But I think the cost is fair for that type of amp. See review here.

Have you tried the electrostatics with a balanced source and amp? Electrostatic systems are 'natively' balanced, so it would be interesting to run this kind of test. The fact that Stax tends not to use standardised connectors, slows down the other manufacturers with producing an alternative balanced amp for those beasts. ..: :..

Yes. I have a friend who runs a recording studio. He's using it with the hd650 all the time as a reference system. So if you are a transparency lover go with ss, if you love colouration go for tubes. That amp is a perfect match for the edition9 too.

Ever tried with a balanced drive? If, like me, you're on the 'transparence' side, you will love this amp.
