Inherit from UD-01, the UD-01 PRO is also based on Burr-brown PCM2702E DAC chip architecture, Burr-brown OPA2064 low pass filters, and the DC servo uses low noise op amps to assign DC servo circuit and to prevent sonic impairment by coupling capacitors.
The differences are UD-01 PRO upgrades power design from switching adaptor to the build-in linear power, and it adds 1ppm TCXI as clock x’tal.
