Bifrost 2/64 is a complete re-thinking of what an accessible DAC can be. With full hardware-balanced topology, balanced and single-ended outputs, remote control, Schiit’s unique True Multibit™ architecture with a time-and frequency-domain optimized digital filter, NOS mode, and our own Unison USB™ input and easy-to-upgrade Autonomy™ platform, Bifrost sets all the standards.


  • Top-Of-Class Hardware Balanced Design
    Just like our range-topping Yggdrasil, the Bifrost 2/64 features a fully hardware balanced architecture. This means four 16-bit DACs total, with one DAC for each phase. You can expect the same stellar performance from both the XLR and RCA outputs, so Bifrost 2/64 works seamlessly with your system.
    Featuring Schiit's Unique True Multibit™ — and NOS
    Like all Schiit True Multibit products, Bifrost 2/64 uses completely unique D/A converters and our proprietary time- and frequency-domain optimized digital filter. In the case of Bifrost 2/64, four DAC8812 D/A converters—the same basic chip used in Yggdrasil Less is More—do the conversion, while the digital filter is implemented on an Analog Devices SHARC DSP. You can also choose non-oversampling mode (NOS) to bypass the digital filter entirely.
    Unison USB™ is USB, Elevated
    Bifrost 2/64 features Unison USB, our own USB input based on a general-purpose PIC32 microprocessor, using precision local clocks and complete electromagnetic and electrostatic isolation. No more off-the-shelf USB—this unique, UAC2-compliant input provides the highest performance and lowest power draw of any USB input we’ve offered to date. 
    Easy Upgrades with Autonomy™ Architecture
    Slide-in hardware modules and a MicroSD card slot means this DAC never has to come back to Schiit for upgrades. Compare this to other DACs, even DACs costing many times more—only Bifrost 2/64 provides complete hardware and firmware upgradability. All original Bifrost 2s can be upgraded to 2/64 with a new card and firmware, available on our Upgrades page.
    Designed and Built in California
    The vast majority of the total production cost of Bifrost 2/64—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Chassis are made minutes from Schiit Audio facility. PCBs are done just over the hill from us. Transformers are also made in California.
