Welcome to the exaDevices DIY website

We design and build ultra high-end audio components for do-it-yourself projects

We are pleased to introduce the exaU2I Asynchronous USB to I2S Interface. It is
the first affordable device on the market capable of streaming multichannel 384 kHz and 352.8 kHz DXD in full 32 bit resolution from a PC to a DAC with professional mastering quality.

Another groundbreaking first is the support for DFF DSD64/DSD128.

exaU2I will work with most DIY DAC boards with I2S input. We tested and perfected our design using a DAC based on the ESS Technology ES9018 Sabre32 Reference chip.

exaU2I Multichannel Asynchronous USB to I2S Interface

exaU2I is the missing link between a PC and the I2S input of your DAC. It is designed for use in high-end DIY audio projects aiming to achieve sonic performance that rivals traditional audiophile grade gear.

Asynchronous operation is achieved by using fast FPGA control core, 256 kB FIFO memory buffer and proprietary ASIO driver.

The ASIO driver provides automatic sampling rate switching and bit-perfect data transfer.

Galvanic isolation of the I2S output from the FPGA core and the USB ground virtually eliminates jitter and common noise originated by the PC.


exaDevices delivers innovative and alternative solutions for highest-quality music playback to leading-edge DIY enthusiasts.  Our products are built and supported for personal hobby use only. Commercial use, duplication or distribution in any form is not permitted.
