This switching power supply is also suitable for the operation of audio components such as headphone amplifier. I use it specifically for the KHV Musical Fidelity V-CAN, because the orig. PSU this provide a stabilized voltage. This power supply has no buzz / beep & the headphones on KHV also no hum. Am fully satisfied. But I have the power supply immediately after receipt with load resistors (48 / 24Ohm) several endurance tests (8-24Std.) Subjected, to make sure that it is really ok, and it can therefore in principle a friend.
