My Sprout is one of the Kickstarters and has broken in nicely and plays flawlessly, almost. In the past month I have noticed that it has a tendency to “pop” when I turn the volume knob after it has sat for a few hours or longer. I assumed that this is just built up static due to the drier weather. This morning when I came downstairs there was a faint buzzing in the left channel speaker. When I turned the volume knob (no music was playing) a notch or so, it popped once and the sound disappeared. Should I be worried?
For the record, the Sprout is plugged into a dedicated grounded circuit using the supplied PSAudio “red” audiophile power cord.
