RE: 3B SST...

Good Post!

I have no problem with injecting test signals after an input filter, or any place else for that matter to evaluate a system's response. I also believe that using square-waves and a scope are far more likely to get you to the root cause of audible problems than peering in the frequency domain with a spectrum analyzer, especially an FFT one that doesn't go very far out-of-band.

All "properly designed" systems need to make a reasonable attempt to not accept signals that they can't handle. I think the best case is to have enough bandwidth margin to allow a simple RC LPF as the dominant pole and still be high enough to not mange the treble.

Regards, Rick
