Atmasphere responded and explained that many phono stages use *active* negative feedback to reduce measurable distortion, but as the signal is recycled through the feedback loop, it lengthens the duration of the ticks and pops, making them louder and longer than they occur on the record surface.I did used to think that was why- but it turns out it really has to do with stability in the design. So feedback isn't the culprit: poor overload margin and poor resistance to RFI are.
Our little UV-1 preamp employs feedback yet no ticks and pops.
In a nutshell, proper use of stopping resistors, good layout and blocking RFI at the input all contribute to a stable design. As I have often mentioned before, if the design is stable the need for loading resistors (if used with LOMC cartridges) won't be needed either.
