I've wanted to get my hands on one of these babies for a long time! The articulated tonearm is a unique approach to tangential tracking, the build quality is awesome, and it's gorgeous. The sound isn't anything to write home about at the moment, but I know the problem is a mediocre Shure cartridge. I have an Ortofon X3-MC high output moving coil that I hope to install soon. I'll keep you posted.
I told you I had an idea, but I wasn't the first. When I told the guy I bought the Energys from what I planned to do, he told be it would work well, because he'd tried it. The tweeters come from Sound Dynamics (made by API, like Energy), and were used in 2 way systems with woofers as large as 15 inches. This told me that the tweeters must be capable of being crossed over low, an important thing to consider when replacing a hyperdome.
The system sounds fantastic, exceeding my expectations. I've been enjoying them with all kinds of music, from delicate to very heavy.
