Oooh ... That high pitch noise that is coming from the power adapter/brick of my SMSL class D amplifier, they are so annoying. Yes, coil whine. It is audible even from 6 feet away. The worse part of this all: this problem began on the 13th month after purchase. So no warranty claims here for me for a 12 month warranty only.
A replacement power adapter from SMSL is not cheap either. Quite hard to find too. A quote from the seller that sold me this amplifier says that it costs RM 100. A bit too steep for me. Plus there is no guarantee that the same thing will not happen again weeks or months down the road.
So what am I to do?
I did try a couple of things.
