I can be sure the settings aren't the same because I re-calibrated after introducing it to the system. I've also been trying it with and without Audyssey. I wasn't using it before, and I can't say for sure whether it was engaged or not when I was noticing the bass, so there's that, too. In any case, I'm happy with the quality of the sound at higher volumes. Doesn't feel like it's becoming compressed when I'm pushing it.
