Huron Upgrade

Transform your DirectStream series DAC with the latest

Built in Boulder
Huron is now available for download for the DirectStream DAC and DirectStream Junior

Since its introduction almost 3 years ago, the DirectStream DAC, and now DirectStream Junior, have altered the expectations of audiophiles worldwide, and proven its ability to be upgraded in the field at no cost to its owner–obsolescence is obsolete. The Huron operating system upgrade provides further reductions of jitter sensitivity, reduces in-band noise by 3 dB and drops ultrasonic noise by a staggering 18 dB, and increases upsampling to DSD by a factor of 2. The sound quality of Huron is the best in a continuing assault on the state of the art in digital audio—as well DACs with Bridge II will soon support full MQA unfolding. The upgrade is free via download and self-installation or by purchasing this pre-formatted SD card, or USB memory stick (DSJ only) delivered to you ready to install. Instructions for the upgrade are here.


DS Series DAC Huron Upgrade

Product Description

Huron is the latest operating system for DirectStream DAC and DirectStream Junior (DSJ). Available as a free download or purchase as a pre-loaded card, or USB memory stick (DSJ). Huron transforms DirectStream DACs into even higher performance level yet achieved. Huron improves the sound of Red Book audio as well as DSD and high-resolution PCM. Blacker backgrounds, improved image separation, better clarity and more lifelike presentation of music are its benefits.

Huron is a free upgrade for DirectStream and DSJ owners and will be required when full MQA and Tidal support is rolled out with the forthcoming Bridge II update later this month.

Install the new Huron operating system just for the sound of it, or to add the benefits of MQA and TIDAL to your music system.
