Finally finished my DAC END 24, sounds fantastic now I can hear more details, very pleased with results. at begining I had hum issues, then I check all my wiring again, but no sucsess. hum issues I had on DAC pcb solderred ballanced input connector, one of two holding screw holes gas ground connection. Is there anyone else had same issues? thank you.

Hi Quanghao, hum causes balaced input socket screw. I had to remove screw temporary to avoid hum.
