Audio GD Master 19 Preamp & Headphone Amplifier AudioGD Audio-GD Amp

Description

This Audio-GD Master 19 was used as headphone amp in my library for both balanced and un-balanced phones, it is so powerful that the very hard to drive Hifiman HE6se sounds easy and forceful.  Occasionally it was connected to a speaker system, and produced very nice music out of a pair full range drivers with a 10W class A power amp.
The unit had low hours, and is in excellent working condition.  There are two or three very small and light paint chips on the bottom side of the case (I think they have been there when I received the unit from the factory) - see the pictures.
I paid extra to get the aluminum full size remote (battery not included).  Still have the original package, and power cable (you might want to use a better one than the stock cable).
