Henry Audio USB DAC 128 mk 3

Henry Audio

We have now got another product from the DIY world available on hifimediy.com, helping to make it available to customers worldwide.

The Henry Audio DAC started as a DIY project back in 2011 aiming to develop a USB receiver and driver. The original name “QNKTC” has since evolved into a ready made product. It comes with a simple enclosure and down to earth features.
Head engineer and force behind the project is Norwegian Børge Strand-Bergesen, who has a long background in electronics development and digital audio circuits in particular.

The Henry Audio DAC mk3 is built around the Atmel AVR32 MCU that runs on open source firmware, and the AKM4430 DAC chip. Great emphasis is put on the power supply parts and design of this DAC. End users can also further experiment with the power supply part as there are lots of internal headers available.
This DAC can further benefit from being used together with our USB Isolator that provides galvanic isolation to separate the computer ground from the connected USB device. The high-speed isolator is required to enable UAC2 that is needed to play sample rates above 96/24.

USB Cable is NOT included!
We can provide one, but it will ship separately from China:
