As I was listening to the Trinnov demo in RBH's booth, I was told about the company's brand new subwoofer amp, the SA-500, which provides 500W of class-D power. It's so new that only three exist, which were powering the company's 1010-SXN/R sub and the bass portions of two 8300-SX/Rs at the front left and right, and as I said in the Trinnov post, the sound was excellent with no hint of bloat. The rep didn't have pricing or availability.
