SCHIIT YGGDRASIL+ OFFERS THE BEST PERFORMANCE WITH PROPRIETARY TECHNOLOGIES
Yggdrasil+'s unique True Multibit™ architecture combines integrated Multibit D/A converters with a proprietary time- and frequency-domain-optimised digital filter. Together with the convenience of remote control, switchable NOS mode, and a fully modular platform, Yggdrasil+ gives you the best performance.

AVAILABLE IN TWO OPTIONS TO GET THE BEST POSSIBLE PERFORMANCE ACCORDING TO YOUR NEEDS
Yggdrasil+ is available in two different flavours: Yggdrasil Less is More & Yggdrasil More is Less. Yggdrasil Less is More provides even better performance for a lower cost than the original Yggdrasil. It features four TI DAC8812 16-bit D/A converters. Yggdrasil More is Less in contrast to Less is More, is the best-measuring integrated multibit DAC ever. It uses four TI DAC11001 20-bit D/A converters. If you think multibit DACs can’t measure well, this one’s for you—approaching -120dB THD+N.

GET THE BEST OF BOTH WORLDS WITH TRUE MULTIBIT ARCHITECTURE
All Yggdrasil+ versions use Schiit's True Multibit architecture, a unique combination of their proprietary time- and frequency-domain optimised digital filter and integrated medical/defence grade multibit D/A converters. The DSP-based digital filter used by Yggdrasil has a closed-form solution since it interpolates accurately; while keeping the original samples. You can only get the finest NOS and upsampling designs with this digital filter.


OFFERS FIVE DIGITAL INPUTS FUSED WITH UNISON USB™ INTERFACE
Yggdrasil+ isn’t just about ultimate performance. At the same time, a team of design engineers at Schiit included five digital inputs, including their own Unison USB™ interface with complete electromagnetic and electrostatic isolation. Ease of access is assured with standard remote control, with provided features like absolute phase inversion and NOS mode so you can optimise your system and recordings.

FULLY MODULAR ARCHITECTURE ALLOWING YOU TO REPLACE AND RECONFIGURE THE DEVICE
Only Yggdrasil+ offers the flexibility and assurance of a truly modular architecture, both hardware and firmware. Every board, from input to output, is easily replaceable, and the chassis is reconfigurable for future expandability. This unique upgradability gives you phenomenal performance and longevity.

The Schiit Story
The story of Schiit Audio begins with two veteran audiophiles Jason Stoddard, formerly of Sumo, and Mike Moffat, formerly of Theta coming together to shake things up a bit. Both of them have extensive experience in developing lots of audio and A/V products including the Andromeda III, Cobalt 307, DS Pre and Angstrom 200. From power amplifiers, I/V conversion stages, D/A converters, relay-switched stepped attenuator volume controls in preamps to developing the first DTS home theatre surround processor on the market, Schiit Audio has developed a lot of audio products over the years.

Getting into Designing Headphones
Headphones are the need of the hour everyone who likes music uses a headphone. Therefore Schiit Audio moved to develop personal audio equipment while continuing to design a speaker-based system which includes the industry-leading preamps, amps and DACs. So right now Schiit Audio has a plethora of audio products ranging from personal audio to speaker-based systems. Schiit designs affordable audio products that bring happiness in your lives.

True Multibit DACs and Unique Digital Filter
Unlike ordinary DACs that use delta-sigma, NOS (new old stock) D/A chips, multibit chips, high-cost R2R ladders, Schiit uses unique DSP-based closed-form digital filter which improves the sonic performance of the multibit DAC. Therefore the Schiit's multibit technology brings all of it together using the current-production, medical/military grade D/A converters.

Innovation in Analog
Schiit has opted for an innovative approach for the analog side as well. Even the most affordable Schiit headphone amplifier is a miniature, fully discrete, DC coupled, current-feedback power amplifier. Schiit is credited for introducing Continuity output stage to solve the issue of transconductance droop which was common in Class AB amplifier design. Schiit has also developed balanced topologies like Nexus in Ragnarok 2 and a perfect combination of tube and solid-state with Coherence in Lyr 3.

Designed with High-End Materials for Durability
All the Schiit products are designed for solidity and durability. Even the smallest of the products are made of aluminium and steel while the larger products are made of high-end C core transformers, power supply filtering and low-noise control. All the products have to go through severe testing procedures including the latest APx555 audio analyzer and Avermetrics analyzers. Every product from Asgard and up goes through burn-in to address the issues faced during the initial period of usage. Schiit takes care of all the service and support requirements so that you can concentrate on great sound.
