I've already described a Totem product as best sound of the show, and I haven't changed my mind, but the Induction Dynamics room was just as good. So it's a tie. Big, smooth, transparent, addicting. The big fella is the ID1.18 and the center is the C1.8. Other models, including in- and on-walls, complement the ones we heard. There's no digital room correction built in--the sound is just plain old great engineering with patented crossover, timbre-matched drivers, external sub amp, etc. You get the best qualities of a big speaker (massive soundstage, top-to-bottom accuracy, meaty bass) with the best qualities of a small speaker (timbral fidelity, phase coherence, subtlety, comfort)--in a, well, pretty huge package. But it sounded stupendous. A 5.1-channel system would be roughly 20 grand and the ID folks will match your existing speaker finish or create whatever you desire on a custom basis. Wow, wow, and wow. Also, wow.
