To answer some recent questions... Frank, I agree, I'm sure the distortion is not in the ADC/DAC components (nor software, nor input stages) either, because I don't hear it at the 5K PA's *driver stage* output, which is well after the output DAC (ref: 1st half of 6 July recording). The problem only pops up at the output of the *final* stage.
And this is why (per Dale's comment) I don't think it's a problem with the balanced line input. If this input was causing the audio to sound grundgy, then I'd expect to hear it at the PA Driver stage, too (1st half of 6 July recording). But I don't. (But maybe I'm missing something really obvious, or doing something wrong. Suggestions?). Per Jim - this 5K (my second one) is right out of the box, and I didn't recal PA bias (I shouldn't have to, right?). By the way, I had this exact same problem with my first 5K, too, and I could not fix the problem despite numerous bias recalibrations as well as experiments with various bias settings, so I'm skeptical that recalibrating bias will have any appreciable effect. Still, it wouldn't hurt to give it a try. I'll try to get to this tomorrow.
