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 our first product.) Asgard 3 features our unique Continuity™ topology that extends the benefits of Class A output, and accepts all the same modules as Jotunheim and Lyr 3.

The Strong, Silent Type

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!
