USB, Elevated: Introducing Unison USB™

Unison USB™ Upgrades Now Available for All Schiit Upgradable DACs

January 28, 2020, Valencia, CA. Schiit Audio announced the immediate availability of its Unison USB™ input for all of its upgradable DACs (Bifrost, Gungnir, and Yggdrasil.) Unison USB is Schiit's unique, proprietary USB input that is the result of 2 person-years of development. Running on a general-purpose Microchip microprocessor (rather than a typical XMOS or C-Media solution), Unison USB provides superior UAC2 performance at very low current draw from the host, as well as complete electromagnetic and electrostatic isolation.

"Unison USB is designed to do a single thing, and to do it better than anything else: deliver exceptional PCM audio performance," said Mike Moffat, Schiit's Co-Founder and head of digital development. "As a result, Unison USB is now our preferred input over SPDIF. It's not 'just as good,' or 'close.' It's really better than SPDIF. And yes, that's me saying this, not an alien pod person."

Unison USB debuted in Schiit's all-new Bifrost 2 DAC last year. Now, Schiit is bringing Unison USB to all of its upgradable DACs: Bifrost, Gungnir, and Yggdrasil.

All models of these DACs, regardless of age can be upgraded to Unison USB. Gungnir requires a motherboard firmware re-flash, which means it needs to come back to Schiit for the upgrade. Bifrost and Yggdrasil can be upgraded by any competent technician, or can be sent back to the factory, at the owner's choice. If a customer chooses to have Schiit do the upgrade, they can continue to enjoy their DAC until it is ready to be upgraded, thanks to Schiit's upgrade queuing system.

All new Gungnir and Yggdrasil models will now include the Unison USB input standard. Gungnir cost increases to $899 for the delta-sigma model, and $1299 for the Multibit version. Yggdrasil increases to $2449.

The Unison USB upgrade is available for purchase today at Schiit.com, for $150, or for $200 including installation by Schiit.
