Do any of these devices have switching power supplies, perchance?
Pass Labs XONO's hum sound
Hi folks,
There is a small hum sound coming from the mid and low driver from my speaker, I then disconnected the input cable but it still there, and I tried to float the earth wire of the power cord still make no different, is this normal ？
