I had a bit of a listen, indeed quite good, especially at the price. Can't believe how light they were. They hung a bit low over my ears
There WAS a slight edge to the sound, not really sibilance, but like a little sheen to the sound (EDIT: I wouldn't have described them really as having warmth, but "edge" may be too strong of a word, implying brightness, and that's not what I meant). But bass was very good for an inexpensive set, and the piano bit I heard was very good.
Drew told me that this uses a 5-pin Stax connector, and should be able to be driven by a Stax Pro amp (though the amp there was only 400V he said).
Still, for $800 with the SS amp, it should provide a great intro to stats. As I mentioned at the show, my experience with the Koss ES is limited, but based on my (sometimes suspicious old-man) memory, this may be better overall....!
