The processing couldn't change continuously - unless you want to permanently mic your space so it can monitor room interactions. Like Audyssey or any other system, Trinnov is going to be something that you run once and that creates a set of adjustments.

As for a good calibrator, you get into several questions. First, as Altec points out, you need to find someone good. That's a significant trick. Second, you need to provide that good calibrator with the tools to conduct that calibration. Does your processor offer manually adjustable EQ's for each channel so that the adjustments can be made in the digital domain? If not, are you providing eight analog EQ's between processor and amp to adjust each channel individually? Third, how do you balance all that is involved in manual EQ with what would be involved in room treatment in lieu of room correction?
