fraterOiramWow, unbelievable. Thanks for the report sir. If you don't mind a question; do you suppose a "usb power conditioner" may help escape this noise by-product of the charging operation? Also, do you suspect that changing a charging source, like to a Samsung phone charger; might alleviate this condition?
CaizHey caiz, unfortunately I've never used usb power conditioner so I wouldn't be able to answer that question. It might be worth a try, surprisingly this amp holds a lot of battery power so I dont really find myself using it while charging.
I must say it powers my Hd 58X wonderfully
