Asgard 3 is a highly powerful, highly affordable, modular headphone amp and preamp that gives you a complete, single-box solution for all your desktop needs. It’s a re-thinking of the headphone amp that started it all (for Schiit, anyway—the original Asgard, introduced in June 2010, was the first Schiit product.) Asgard 3 features the unique Continuity™ topology that extends the benefits of Class A output, and accepts all the same modules as Jotunheim and Lyr 3.
Asgard 3’s all-new Continuity output stage delivers 3.5W into 32 ohms—a whopping 3.5X more than any previous Asgard—while also running 500mW of Class A bias. What this means is you have tons of power for virtually any headphone—and, since full power is delivered to the ¼” jack, you don’t need balanced headphone cables to take advantage of it. At the same time, Asgard 3’s low noise floor means you are ready for the most sensitive IEMs.
A Complete Desktop Control Center
Select from the internal card or rear-panel analog input, and pick high or low gain with convenient front switches. Connect the preamp output to your powered monitors for a complete desktop system—or use it as a front end to your speaker power amplifier. Asgard 3 provides all the flexibility you need.
Customize to Your Specific Needs
Want more than an amp, without a bunch of boxes on your desk? Choose an internal DAC module to create an all-in-one system:
• ES9028 DAC. Choose the ES9028 module with Unison USB™ for a world-class delta-sigma DAC for $100. • True Multibit Unison USB™ DAC. Or choose our own True Multibit technology, with AD5547 DAC and proprietary DSP-based digital filter, as well as our own Unison USB interface, for $200.
Choose the ES9028 module with Unison USB™ for a world-class delta-sigma DAC for $100 more. Plus, this unique modular design means Asgard 3 won’t be dumpster-fodder when technology changes—just swap a card!
Designed and Built in California
The vast majority of the total production cost of Asgard 3—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. The chassis are made minutes from our facility. PCBs are done just over the hill from Schiit Audio, or done in NorCal. Transformers are also made in California. You get the picture.
