is it compatible with topping d20?
i'm interesting in this product because this power supply allow to use ground 3pins cable. The original power supply included in the box of d20 hasn't ground pin. so when i touch my amp's aluminium chassis, there is some kind of electrical flow. also when i touch this chassis, i can listen hum noises who are deliverd by headphone to my ear. and i always serch a 15v 1a power supply with ground pin but it wasn't existed on market. and this product has 15v 1a and ground pin. but i'm not sure if it is compatible with my d20 topping dac.
