NuPrime Evolution DAC-2

Description

A World class DAC/Preamp for the most discerning systems

The NuPrime Evolution DAC-2 utilizes dual ESS Technology 32-bit audio DAC ESS9038Q2M to decode independently left and proper channels to improve channel separation and reduce overall noise. It supports nine digital inputs and two analog inputs for complete system flexibility. The power circuit uses C-Core transformers to meet the highest performance requirement of the NuPrime Evolution Series. PSRC IC chip provides sampling rate up/down conversion from PCM 44.1kHz to PCM 768kHz and DSD64 to DSD512.

Ultra Clean Power Circuit

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 60,000uF) using specialized capacitors, supplies ample and stable power to the analog and digital circuitry.

A Reference Class Preamp

The EVO DAC-2 includes a reference class preamp that utilizes Nisshinbo Micro Device’s MUSES8820 operational amplifier and MUSES72320V electronic volume as its preamplifier circuit architecture. The MUSES8820 is optimized for high-end audio equipment, producing the finest sound quality that emulates the live performance of an orchestra in a hall. On the other hand, the MUSES72320 is a 2-channel electronic volume control designed with advanced circuitry and layout for high-end audio applications. It has low noise and distortion characteristics and utilizes a resistance ladder circuit for highly linear volume control of hi-fi audio systems. Together, these components make the EVO DAC-2 an exceptional preamp, capable of producing a high-quality sound that accurately captures the nuances and details of a live performance.
