I’ve had this issue ever since I’ve had the Hugo2: when I plug in my IEMs (Thieaudio Legacy 9) I get a hissing noise. Even when the volume is off. This hissing noise doesn’t get any louder even when the volume is at maximum (white light). I don’t USB power the Hugo2, so it is running on battery power.
I use the Legacy 9 on the go with the M11Pro SS, and I don’t get any hissing noise there. I plugged in the Hifiman Ananda this morning and there was no hissing. The two year warranty ends mid September, which Is why I’ve decided to address this issue now. Even though I could live with the hissing, I would like to know if it is normal.
And even when using a 5V/2A charger, It takes over 6 hours until the charging light turns off.
It all comes down to: would you guys, in my place, go through the process of sending them in for a repair?
A sincere thanks for any help; it is greatly appreciated Thank you for reading.
