Tbg: I heard them at Audio Federation in Boulder, CO. I've actually now spent many hours listening to them with 3 different amps (Edge Signature something, Audio Note UK Kegon, Lamm ML2.1). As much as I'm a Lamm fan (and owner), the Kegons are just magical amps. Before I heard the Triolons, it was my opinion that the law of diminishing returns hit hard not far into the 5 figure range. Now I know, at least in one case, that you really do get what you pay for with top end gear. Of course, the Trolons may just be the exception, I still haven't heard anything else on the extreme high end that is really *that* much better than the good stuff you can get for 15-25k.
