I sat in the "sweet spot" at the Axpona demo for this product. It sounded fine, and "different" but also seemed very gimmicky overall. They played some stuff that had a bunch of flying insect sound effects and again, it was cool in the same way that Dolby Digital (AC-3) was in the early days of home theater, when discrete surround channels were implemented, but (to me, at least) it didn't make music more enjoyable.'
This might be due to the hype effect, wherein everyone says something is the cat's PJs and my expectations were too high.
