My two cents...
Look at the design of the K-1000, and the research and care taken to accomodate human ear anatomy and related aural cues. There is no hint at compromise for marketing, comfort or the "you-look-like-a-fool-wearing-those," factor, let alone the fact that you need to drive them with a real, balanced amp. There was no reliance on conventional high end audio wisdom...no chrome, precious metals, organic varnish over rare woods, no tubes, or any of the other male jewelry that usually appeals to those at a certain price point. Nope. These things are red, and metal grilled and damned ugly on your head.
In short, I don't think there is any transducer on this earth that rivals the K-1000 for being a balls-to-the-wall radical assault by engineers, who knew what they were doing, on the conventions and compromises in other, um...headphones...earspeakers...transducers...what ever you want to call them.
If they sounded like cardboard between doughnuts the K-1000 would still be notable for the fanatical devotion to doing something radically and market defyingly different. That they sound closer to music than just about anything out there makes it all the more the shame that they are going out of production.
Your ears and mileage may differ of course.
