NuPrime Hi-mDAC - Compact headphone amplifier

NuPrime Hi mDAC is a really slim DAC/headphone amplifier with low power consumption and is easily connected to your computer or mobile. Capable of PCM 32/384 and DSD256 decoding.

HEADPHONES

Paired with a good pair of IEM's, like the Fearless S8F, or even the BGVP DM6, I'm pretty sure that most of you will be blown away and realize how far we have come! A recommended purchase!

The Hi-mDAC outperforms anything in its price class and compares favorably 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.

COMPATIBLE

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.

CONVENIENT

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.

OUTSTANDING SOUND & BUILD QUALITY

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 machined from two pieces of aluminum with precise mechanical specifications.

• USB port
• Works with Android (4.1 & above with OTG), iOS (with camera adapter USB cable), Windows 7/8/10, & Mac. Windows device driver download is required; other devices do not need a driver.

Accessories

• USB-A to USB-C cable included

Standard micro USB or lightning cable cannot be used to connect Hi-mDAC to Android or iOS device respectively. They were designed to connect a computer to the mobile devices.

Use a microUSB Male to USB Female OTG adapter with the USB-A to USB-C cable to connect Android devices to Hi-mDAC.

Connecting Hi-mDAC to iOS Devices

Use Lightning to Camera Adapter cable (if external power is needed for extended listening, use the Lightning to USB3 Camera Adapter cable) and the USB-A to USB-C cable to connect iOS devices to Hi -mDAC.
