Hello!
I can not connect my power cord correctly to my Topping pre90 preamp, it does not fully enter.
I found that the ground pin is longer on the preamp power socket, than Line and Neutral pins. It keeps the plug from entering all the way, and too often the power connection is lost due to subtle movement.
Since the pin holes in my audioquest power cord are of equal length, I am about to sand that ground pin shorter.
Do you think this longer pin is a defect, or does it have some point, other than keeping my cord only half way in?
🙂
