I was fiddling around with my Keces DA-152 DAC/amp because there was a lot of noise and I was trying to figure out what was causing it. Stupid me wasn't thinking and I switched the input voltage from 230V to 115V. When I turned it on it died in a second. There was no sound or smoke, it just died. Now it won't power on. I'd like some advice on how to repair something like this, whether it's only affected the power supply of the unit or the entire thing, and if there's something I'm overlooking. Thanks in advance.

most likely, the noise is due to muting transistors
as for it burning out, hopefully they fused it the psu.. I'd they they would.. but who knows what silly things audiophiles may do in pursuit of -transient- hahahaa.
Take it apart and look at that psu board.

How would I look at the PSU board?

AFAIK, the round silvery object is the power supply? Although I almost definitely may be mistaken. I've been told to check the voltage across the unit to find which component has died so I'll need to borrow a friend's multimeter.

OK, I received word from their customer support that only the fuse is damaged, and that I need a 0.5A fuse to replace.

Told ya.. hahahahaha..
the fuse is probably on that small board to the left. you see that tube looking thing ontop, the whitish thing.
