[sdiy] Looking for advice about powered reference monitor problem

[Shawn Rakestraw]

Thanks for the comments and general direction. I believe you and genuinely
hope that it is a solder joint. That would be a simple fix by relowing the
joints. I can't help but wonder, would a cold solder joint suddenly form
after 15 years of use and also never being moved for 10 years? I tried
checking the noise floor (with my ears) and it seemed the same for both
monitors. Maybe it is the input signal. I will investigate more!
