I use the BW control a lot as most of my work is weak signal CW. There was no popping before, and my ears are "on max gain" with weak signals, that are at or near the noise floor. The popping is VERY annoying and at times it "hurts" the ears when digging for signals and changing the BW control from 200 Hz to 150 Hz, to 100 Hz and finally to 50 Hz. The popping is present as I rotate the BW control back to wider bandwidths also, but the popping stops once above 200 Hz bandwidth.

Yes, I have it too, and I didn't notice it before installing the new synths. Doesn't bother me.
