NuPrime Audio Introduces the Remarkable uDSD

NuPrime Audio takes pride in introducing the NuPrime uDSD, an especially well priced, high-performance USB-powered portable DAC and headphone amp. Supporting the latest high-resolution music formats, the 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. With an output of up to 140mW x 2 @ 32 ohms, the uDSD’s powerful headphone amplifier is capable of driving today’s most sophisticated headphones.

The uDSD is equipped with one Coaxial S/PDIF and 2V RCA Analog outputs for compatibility with a broad variety of systems. Of equal importance, with its native DSD format decoding capability, the uDSD is ideal for upgrading existing high-end non-DSD DACs. 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.

In total, the uDSD is one of the most advanced USD-powered portable DACs on the market. Since no external power supply is required, audio enthusiasts, musicians and recording engineers can employ the NuPrime uDSD with a laptop for work or enjoyment anywhere.
