Heed all warnings and safety information in these instructions and on the product itself. Follow all operating instructions.
Do not use this unit near water.
You must allow a minimum 10 cm or 4 inches of unobstructed clearance around the unit. Do not place the unit on a bed,
sofa, rug, or similar surface that could block the ventilation openings. If the unit is placed in a bookcase or cabinet, there must
be ventilation of the cabinet to allow proper cooling. Keep the component away from radiators, heat registers, stoves, or any
other appliance that produces heat.
The unit must be connected to a power supply only of the type and voltage specified on the rear panel.
Connect the component to the power outlet only with the supplied power supply cable or an exact equivalent.
Do not modify the supplied cable.
Do not route the power cord where it will be crushed, pinched, bent, exposed to heat, or damaged in any way. Pay particular
attention to the power cord at the plug and where the cord exits the back of the unit.
The power cord should be unplugged from the wall outlet during a lightning storm or if the unit is to be left unused for a long
period of time.
Immediately stop using the component and have it inspected and/or serviced by a qualified service agency if:
• The power supply cord or plug has been damaged.
• Objects have fallen or liquid has been spilled into the unit.
• The unit has been exposed to rain.

1. Introduction
To meet the highest performance requirement of the NuPrime Evolution Series, the power circuit
of Evolution DAC has been redesigned from the ground up using C-Core transformers and AC filter,
in addition to the DAC circuit. It utilizes one of the world’s highest performing 32-bit audio DACs,
the ES9038PRO, and NuPrime PSRC IC chip to not only decode but also provide sampling rate
up/down conversion from PCM 44.1kHz to PCM 768kHz and DSD64 to DSD512.
Ultra Clean Power Circuit
AC Filter
To get the cleanest and most stable power to the circuitry, no expense was spared when designing
the power supply section of the Evolution DAC. The AC inlet goes right to a filter, which reduces the
AC high frequency line noise by at least 20dB in the 100kHz to 5MHz region.
C-Core Transformer and Large Capacitor Bank
The filtered AC power is then fed to the AC power supply that utilizes C-Core transformers which
has less stray flux than conventional ring type transformers. The stainless steel enclosures for the
power supply provides shielding to minimize the transformer noise interference affecting other
sensitive circuitry.
A large capacitor bank (around 70,000uF) using specialized capacitors, supplies ample and stable
power to the analog and digital circuitry.
Discrete Transistors and Changeable Op-amps
Taking things further, the analog section benefits from a NuPrime proprietary power circuitry crafted
from discrete components. This circuitry provides further power stabilization and exhibits a high PSRR.
Hence, the analog section is fed with the cleanest and most stable power we’ve put into any product.
This translates to a superlative gain in audio performance that defines the Evolution series.
The Op-amps used in the analog section are socketed, making it possible for DIY customers to
experiment with different sounds by changing them to other Op-amps.
