Soundlab Ultimates are the ones with a special metal chassis. Didn't really fancy them tbh. While they could have done with more open space (and were running off a Bel Canto system, the new dac and the amps which are 500w each), the thing that could have benefited with more space is more soundstage. They do certain things which are fake - the mouth of the singer is too large, the trumpet and guitar seems too large as well. They have a very typical Stat sound, I prefer the Logan panel more. Quads as well. Where these do better than Logans and quads is that the panel can be more dynamic, it extends low without a crossover, though frankly if those who own hybrids don't mind the crossover, it's not a problem. Even though they have good bass, drums sound unnatural. I personally would stick with a Logan hybrid over this, and definitely the Analysis.
