Efficient board design and top quality parts. This is the “magic” recipe of Mamboberry HD DAC+ v2 and all the Mambo series by Collybia.
ELNA local filter capacitors from it’s audio hi-end series “SILMIK II” at 470uF capacity. No other dac-hat has that capacity.
Ultra low noise 3.8μV power supply from Texas Instruments (TPS7A8701)
Two choices for Ultra Low Noise (jitter) Clocks :
- – Crystek(Hi-End Ultra Low Noise clock)
- – IDT(Low noise clock)
WIMA plastic film capacitors at low pass path
Five ELNA audiophile capacitors around the dac chip
SUSUMU SMD resistors at i2s line at 0.5%-1% capacitance
