The NuPrime HPA-9 is a pure Class-A headphone amp and preamp with low temporal distortion and lifelike sound. The single-ended Class-A design and non-feedback output stage are capable of handling wide fluctuations and range of headphone impedances from 16 to 1000 ohms.
HPA-9 was derived from NuPrime DAC-10H, which won The Absolute Sound Product Of The Year 2015 award. The headphone amp of DAC-10H was compared to high-end standalone headphone amp costing as much as $3000. Today’s best headphones can cost as much as a high-end DAC. Their owners demand a headphone amp that fully exploits their potential. High resolution DAC chips are starting to be incorporated into smart phones and that would further drive the need for high performance headphone amp that can be used with a wide range of in-ear and over-ear headphones. Phono input is included for vinyl enthusiast.

NuPrime uDSD ™
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.
