Most versatile and portable USB DAC (PCM 384kHz & DSD256 decoding)

The Hi mDAC is a portable high-resolution DAC and headphone amp. Capable of PCM 32/384 and DSD 256 decoding, it is ultra-compact and low power consumption and connects easily to your computer or mobile device.

The Hi-mDAC outperforms anything in its price class and compares favourably to digital-to-analog converters and headphone amplifiers costing significantly more. It provides the listener with truly full-range sound with commanding bass and an impressive full-frequency response. The improvement in sound quality is easy to hear.

State Of The Art DAC Chip & Custom USB Chip

Many low cost portable DACs can only decode up to 24-bit/96kHz PCM and do not support DSD decoding. The Hi-mDAC 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, making it the most capable USB-powered portable DAC on the market today!

Hi-mDAC utilizes a new chip CS43131 from Cirrus Logic. The CS43131 combines a next-generation, low power audio DAC with a high-fidelity headphone amplifier to provide a superior system-level audio performance without draining battery life. To minimize pre-echos and ringing artifacts, the CS43131 is designed with proprietary digital-interpolation filters that support five selectable digital filter responses. Filtering options include low group delay with pseudo-linear phase and a fast or slow roll-off. Volume matching of the analog output levels and channel mixing enable a seamless transition between the DSD and PCM playback paths. The onboard low noise, ground-centered headphone amplifier provides proprietary AC impedance detection to support headphone fingerprinting to provide a consistent and transparent audio experience for the end user regardless of transducer impedances or frequency responses.

A NuPrime customized low power USB communication chip together with the CS43131 achieved the previously unattainable goal of a lower power high performance portable DAC & headphone amp device.


The Hi-mDAC is compatible with a wide range of devices — Apple computers and iOS devices, including iPhones and iPads, all PCs and many Android devices.


The Hi-mDAC is one of the smallest high performance USB DACs available on the market today. Measuring just 5.0cm x 2.2cm x 1.2cm, the Hi-mDAC can travel easily in your pocket, backpack or briefcase. With a USB cable that connects to your iOS device or Android, it’s a great way to get improved sound quality from your smartphone or tablet.


If you’ve only listened to music through your existing computer sound card or the built-in DAC in your iOS or Android device, you will find this USB powered external DAC an unmistakable improvement in sound quality. If you have an older external DAC that can only decode 24-bit/96kHz PCM, the Hi-mDAC will allow you to hear and feel more of your favorite music. The superior sound will provide a definite upgrade to your listening experience.

The chassis is CNC machining from two pieces of aluminum with precise mechanical specifications.
