I recently bought a 3-channel B22, which I've been using with my Denon D2000 (25 ohm) and Audio Technica AD2000 (60 ohm) headphones
The problem is, when I plug my headphones in, there is a faint humming in the background. Unplugging the DAC makes no difference, and it can be heard at any volume level.
The humming is especially loud with the Audio Technica AD2000s, and becomes unbearably loud at the lowest and highest volume setting
There is a gain of 8x, but I'm not sure if the noise is because of the high gain... Has anyone else had this issue before?
