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? Select from two different DAC modules, or no module at all to tailor Asgard 3 exactly to your needs. Plus, this unique modular design means Asgard 3 won’t be dumpster-fodder when technology changes—just swap a card! AK4490 DAC Module.

    Choose the AK4490 G2 DAC module for a world-class delta-sigma DAC Multibit DAC Module. Or, choose the optional True Multibit™ DAC Module to get Schiit’s unique digital filter and multibit DAC architecture

    Designed and Assembled in USA
    By “designed and assembled in USA" this is what we mean: the vast majority of the total production cost of Asgard 3—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. Our transformers are also made in California. You get the picture.
