Windom Upgrade

Transform your DirectStream series DAC with the latest

Built in Boulder

Since its introduction almost 5 years ago, the DirectStream DAC and DirectStream Junior, have altered the expectations of audiophiles worldwide, and proven their ability to be upgraded in the field at no cost to their owners—obsolescence is obsolete. The Windom operating system upgrade provides further reductions of jitter sensitivity, lowers audible noise, improves upon the work Ted Smith performed in Snowmass. The sound quality of Windom is significantly better than any iteration before it. 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.

Windom DirectStream Upgrade

Product Description

Windom 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). Windom transforms DirectStream DACs into even higher performance level yet achieved. Windom improves the sound of Red Book audio as well as DSD and high-resolution PCM. Blacker backgrounds, greater instrument weight, wider and deeper soundstage, better instrument separation, improved low level linearity, and far great inner detail that ever possible are among its many benefits.

Windom is a free upgrade for DirectStream and DSJ owners.

Windom is the biggest improvement yet in the DirectStream product line. It shouldn’t take long for you to hear the major improvements, big enough to call it a new DAC. Let your friends know you just got a new DAC and for free, just one of the many benefits of our unique software upgradeable DAC series. And, because it’s PS Audio, we never charge for software upgrades.

Audiophilia

Karl Sigman

The church venue was so apparent with Windom, the singing was more natural since the church venue was now truly part of it, and the singing was less distant—more up front.

Once again, PS Audio has bolstered the advantage of using a software based DAC versus one that has a built in chip. Bravo. Keep at it, I say.
