To make it work you have to provide MCLK , 2x9 Vac and 2x15Vdc . For this I use Kali Recloker , some voltage regulators ( home made) and 1 trafo. Architecture: Velvet Sound I2S THD+N -101dB S/N 123dB Digital filters 4 PCM 384kHz DSD tested : DSD64, DSD128 & DSD256.
Price: 79,00 €
It is working with Terra-Berry DAC2 driver but without hardware volume control. ( If somebody know how to make it work , please help).
