This unit has never been installed in the car and has little used only as sample (by info of last owner). I bought this item for myself in USA at 2008 but never used.
Excellent condition (given the age more than 20 years). Ideal front side on both devices and a few small scratches on back (invisible) side of external unit MDA4000.
This unit is realy High-End for car audio. I think the best in the World. MDA4000 is an exclusive DAC with really R-2R architecture integrated circuit PCM1702. As you know, the next model of DAC MDA5000 don't have R-2R PCM1702, because Burr Brown stopped production of this chip.
All semiconductors inside unit are original !
