That's like saying a driver is slow. How slow? Bandwidth limiting CHANGES the complex impulse response of the system. It does not make it not matter, or benign, just DIFFERENT. And the bandlimiting is quite variable, thanks to the design and implementation of K3 operating controls of the DSP. Also, note that the impulse response is complex -- that is, if we looked at it as a frequency response it would have a phase response too. One of the important and complex problems that Lyle has to solve (and he's solved it pretty well if he doesn't hit the transformers, according to my ears) is a nice phase (time) response.
