A FET output stage is added to the 1387 chip for improved performance. Better dynamic range and musicality with a warm touch.
Three power supplies for optimal performance. 4A for Pi 4, low noise 5V for1387 DAC chip, linear power supply for FET output. Internal shielding to minimize noise.
Beautiful work. Active (like a Pass D1 w/o buffer) or passive I/V? Very inspiring.
FET output is active powered by DC15V original from founder of Lampizator.
