I don't own them, but have notes from HE200? at the Hilton in NYC where the Octwins were demo'd. I recall in particular a track from Peter Gabriel's "So" being played called "Don't Give Up." It's a well-recorded track with both Gabriel and Kate Bush on vocals. All in the room were very impressed with the sound. Then, near the end of this track is a marvelous bass line, and most of us were quite surprised at the quality of the bass these smallish speakers put out. The sound was very tight, well-defined and dynamic. They can get a bit pricey, though, when you are buying two pairs and the required stands.
