Topping D900 - teardown

Great photos!
Unfortunately, I expected a lot more for €1800.
Why another Mickey Mouse power supply?
Why these sound horrible mute chips on the output instead of decent relays? It's not worth the money.

Maybe that power supply is more than sufficient. Maybe those mute chips are in reality transparent.

Yes at my normal listening level -27.5, the D900 III Discrete outputs 1.543, the D900 outputs 1.530.
This is essentially identical.

It's good to see someone else has taken the time to actually do a level matched comparison instead of following what everyone else says.

On the contrary, I did a similar test between the Topping DX9 and Topping D90III Discrete where I was using a RPi digital transport HAT to output SDPIF to both DACs simultaneously, then the DAC outputs into an analog RCA switch box. I regret to inform you that I'm either not a good enough listener or there really is no audible difference between those two DACs.
