Expect this as "safe minimum" with LM6171 in the I/V:
+-40mA for digital (+-5V) +-60mA for analog (+-12V) The real consumption will be less (perhaps half of that). Schematic examples in datasheet are for both "high performance" and "high resolution" on +-5V digital supply. I would say, the larger the voltage difference between analog and digital (analog > digital), the less the possibility of digital interference - but that's a humble theory unless we see the internal diagram of the AD1862 ![]() |

Even with Burson discrete opamps installed I measured less than +/-60mA current draw on the 12v supply.

Why NOS DAC is better?
Because direct comparison often proved better sound. Some describe NOS-DACs as more vinyl-like in their sound. Oversampling DACs can sound a bit ringing, sometimes a bit muted or veiled. If the oversampling has 8x multiplier, then only 1 out of 8 sampling points is the original record information, and the remaining 7 sampling points are derived from an interpolation calculation. How trusty are those 7 calculations? ... what about 32x multiplier ![]() In complex frequencies/music sometimes less information is more, naturalness. Just adding here my thoughts ![]() |

Where did you pick up the input selector board? eBay? Link?

Never mind Vunce. I read a little further and saw the link from Audiophonics.
