NuPrime uDSD ™
MSRP $269 (SGD)






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.





Sound Quality


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.



Flexible Connectivity


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.






Features:

24-bit/384kHz and native DSD 256 support
Discrete USB audio receiver and D/A converter, with coaxial S/PDIF (24bit/192kHz) output
Coaxial output can also stream DoP (DSD64) for long distance transmission of DSD from computer

High-performance headphone amplifier (balanced design)
High voltage 2V analog output (fixed volume direct DAC output)
Coaxial S/PDIF output
High-quality analog volume control
Diminutive size
USB powered, no external power supply required
Works with Windows 7/8 and Mac OS.

uDSD Reviews

"...Reference, appearance, compactness, design, all in the portable DAC with headphone amplifier NuPrime uDSD recalls the DAC previously marketed under the NuForce brand. But if the name has changed, the force becoming excellence, performance followed the same path as the uDSD is capable of playing digital audio files up to 24-bit PCM 384 kHz and DSD files to 2.8, 5 6 and 11.2 MHz…

...very nice sound space and airy restitution, full of life and details…this first DAC stamped NuPrime uDSD is able to decode all types of digital audio file that can be encountered today, even if some of them are very homeopathic way, and this with results sometimes sound a bit bright, but really really good…”,

"...Performance as Headphone amp

vs uDAC-3
- can immediately tell the uDSD is stronger and a cleaner through the whole range
- it's not a matter of energy or detail, just a sense of a haze that is lifted

vs HDP
- almost on par with the HDP headphone out on technical ability
- HDP has more power overall, better subbass presence because of that
- with the Wyrd I would say uDSD has slightly better detail across the board

…It's a really fantastic multi-tool. It was great when auditioning new gear and I didn't want to install drivers. Took it to a local and just fed the Moon Neo 430HA from the coax. I had an Oppo HA-1 on loan and I fed it coax and RCA simultaneously so I could evaluate and switch inputs directly...",
