"Essentially the Evolution DAC seems to do everything very, very well and regardless of how specific or broad your taste in music is, you’ll appreciate more of what you like and maybe even start to expand your horizons."
NuPrime Evo DAC:
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
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.
ES9038PRO DAC Chip
The world’s highest performance 32-bit Stereo DAC (ES9038PRO). State-of-the-art DAC with warmer sonic characteristics.
