Most versatile and portable USB DAC (PCM 384kHz & DSD256 decoding)
The NuPrime uDSD, a significantly advanced hi-resolution USB-powered portable DAC, connects your personal computer's audio to your home stereo, desktop sound system and headphones. The uDSD features direct DAC out, i.e., fixed-analog out, in order to provide better overall sound quality, and in particular, better-sounding DSD. As an added benefit, this arrangement prevents distortion in tandem with receiving units with volume-adjusting capabilities. The headphone circuit, built on a sophisticated balanced design, provides the uDSD with the ability to drive almost any of today's headphones -- a feature that can also be used to drive active speakers.
Supporting the latest high-resolution music formats,the NuPrime uDSD, is capable of decoding sample rates ranging from 44.1kHz to 384kHz (PCM) as well as native DSD decoding ranging from DSD 64 up to DSD 256.
Powerful Headphone Amplifier
The NuPrime uDSD’s powerful headphone amplifier allows the unit to drive the market’s most sophisticated headphones.
Build and Design
A palm-sized aluminum enclosure provides durability and elegant style. With regard to internals or textured aluminum package, the uDSD bespeaks exquisite attention to detail and build quality.
The uDSD comes with Coaxial S/PDIF and 2V RCA Analog outputs for compatibility with a broad variety of systems. With its native DSD-format decoding capability, uDSD is ideal for upgrading existing high-end non-DSD DACs.
