There is one upgrade available for Bifrost 2: the Bifrost 2/64 Analog Card.
This upgrade changes any Bifrost 2 to Bifrost 2/64.
It includes the Bifrost 2/64 hardware-balanced analog card with four TI DAC8812 D/A converters, an SD card with new firmware. You can slide in the new card and install the new firmware yourself; there's no reason to return your Bifrost 2 to us for this upgrade.
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.
Bifrost 2 upgrade card is covered by a 2-year limited warranty that covers parts and labour.
