DESCRIPTION
THE BIFROST — REIMAGINED
The Schiit Bifrost 2 comes equipped with Schiit's unique True Multibit™ D/A converters and their proprietary time & frequency domain optimized digital filter. It has two AD5781 converters that do the conversion while the digital filter is applied on Analog Devices SHARC DSP.
CONNECT EASILY WITH MULTIPLE INPUT & OUTPUT OPTIONS
The Bifrost 2 comes with multiple input & output options. A unique Unison USB offers the best performance with minimum power consumption thanks to its precision local clocks, PIC32 microprocessor and electrostatic & electromagnetic isolation. It also features an XLR balanced output and RCA single output. It comes with a milled aluminium remote control that allows you to choose from various options including inputs, mute and change phase.
UPGRADE YOUR BIFROST, WHENEVER YOU WANT
The Schiit Bifrost 2 is entirely modular and you don't have to reach out to Schiit for upgrades, but can do it yourself. The modules are designed to slide in from the back of the chassis, letting you easily upgrade them. You can use the external microSD card slot to install firmware updates. In short, you get the freedom to improve your DAC whenever you want.

Schiit - Bifrost 2
FAQs
Yes, it was. And it is. For example, and you can still upgrade, say, an original Bifrost Uber to a Bifrost Multibit, and when Unison USB is available for all the current DACs, you'll be able to add that too—
Well, the original Bifrost was around for 8 years. That is pretty much about a millennium in terms of DAC years, or at least about 286 years in dog years. Seriously, look around and tell us how long affordable DACs last before they’re replaced with all-new models—with no option to upgrade. And again, the original Bifrost remains upgradable, and supported. Bifrost 2 doesn’t change that.
Why an iPhone 11? Why a Galaxy 10? Because times change, and our capabilities change with them. Bifrost 2 allows us to give you an all-new platform that is easy to update, when and if the time comes, without having to send it back to us for upgrades.
It’s entirely different:
1. Balanced output: Bifrost 2 now has balanced output, as well as single-ended output, to simplify its integration with your system
2. Remote control: Bifrost 2 now has a remote control for input select, mute, and phase invert.
3. Better DACs: Bifrost 2 now uses the 18-bit Analog Devices AD5781ARUZ D/A converter, rather than the 16-bit AD5547.
4. Better USB: Bifrost 2 introduces our Unison USB—a complete elevation of the USB input.
5. Easier updates: Bifrost 2’s Autonomy architecture means that both cards are replaceable from the back of the product for easy hardware updates, and firmware changes are handled with an external MicroSD card slot.
6. Improved power supply: Bifrost 2’s transformer is larger, and the power supply has more stages of local regulation, for insanely great low-noise performance.
Yes. It controls input select, mute, and phase inversion.
We did. It's an additional $299. It's called "Saga S." There's even a tube remote volume option for $399, called "Saga+."
I’m sorry, but that’s not possible. Literally every single part is different—chassis, transformer, cards, etc. However, you can still continue upgrading your Bifrost, if you would like. We're also giving every original Bifrost owner or upgrader $100 off the price of Bifrost 2 if you want to move on.
No, we named it True Multibit™ because there’s a lot of confusion over what is really multibit and what isn't. Some companies refer to multilevel delta-sigma D/A converters (like the AK4490 used in the $99 Modi 3 and Fulla) as “Multibit” DACs. While kinda-sorta-maybe is technically correct, this is pretty misleading. 2 to 5 bits of actual resolution plus massive amounts of noise shaping is not true multibit. Hence, True Multibit. We use True Multibit to denote DACs that have 16-20 actual bits, rather than multilevel noise-shaping delta-sigma DACs, coupled with our unique combination of time- and frequency-domain optimized digital filter, based on math first proposed by Western Electric in 1917, and developed into usable algorithms by a team that included a professor emeritus of math and a Rand Corp mathematician. It’s unlike any other digital filter today, and we believe it provides the closest thing to a true interpolation while retaining the original samples as closely as possible.
Cool. You should go buy one. We make a couple of them. They’re also in your phone and Bluetooth speakers.
Well, leaving aside the fact that there probably ain’t nowhere near 24 usable bits in any recorded music, no matter the audiophile cred, if you’re looking for resolution below the 18-bit level, take a look at our measurements, showing Bifrost 2 clearly resolving a -144dB signal. That’s -24 bits. Boom.
How does a 2- to 5-bit delta-sigma DAC do the same thing? It’s magic. We put tiny pixies in each DSP chip. Either that, or we know a thing or two about DSP and dithering.
Unison USB is our own proprietary USB input, not based on C-Media or XMOS or any other off-the-shelf USB receiver out there. Instead, we spent a couple of person-years developing our own code for a standard Microchip PIC32 microprocessor, which allowed us to create a higher-performing USB input than anything else on the market.
UniNot Unison USB. Even Mike Moffat, the famous “friends don’t let friends use USB” guy, prefers Unison to SPDIF.
Yes.
Yes.
We know how you feel.
Unison USB is special because it was developed for a single purpose: to provide the highest performance input for PCM digital, period. It doesn’t have ten thousand un-used functions, nor is it trying to optimize for five different unicorn formats that will probably be gone tomorrow. It also uses very high-quality local clocks and offers complete electrostatic and electromagnetic isolation from the source. It also provides lower power draw and complete UAC2 compatibility.
Actually, the question should be “What platforms support your Unison USB input?” since our Unison USB input is 100% UAC2 compliant (that is, USB Audio Class 2, the accepted standard for USB audio transmission.) So, here you go:
Linux. As in, most popular streamers, from the Sonore MicroRendu to the Salk Streamer. Note “most.” Also most Linux distros that support UAC2 natively will be plug and play. Please note that we cannot provide detailed technical support for Linux.
Windows 10. Yes, Windows 10 only. We don’t provide UAC2 drivers for earlier versions of Windows, sorry. Yes, it is time to step into the present (not the future, Windows 10 has been out for a couple of years now.) Yes, it is time to upgrade. Yes, it’s worth it. Windows 10 is actually a very nice platform.
Mac OSX. From 10.10 on up, Macs are good to go. Sometimes you’ll run into power management problems that will require you to turn off App Nap. Got an older version of MacOS? See the comments on Windows above. Time to upgrade. The software is free.
iOS. From iOS7 on up, iOS devices work with USB Camera Connection Kit, Lightning to USB Camera Adapter, a Lightning to USB3 Camera Adapter, or directly with the new USB-C models.
Android. Most Android devices that shipped with Android M or above will work using a USB OTG cable. Some may require separate player software, like USB Audio Player Pro.
Yeah. We know. But again, we really needed to name this. Because now, no matter the update, Bifrost 2 never has to leave your hands. New firmware? Just plug in an external MicroSD card. New analog card? Just slide it in. New USB card? Same. Again, we’re not planning on a ton of updates, but when there are updates, you won’t miss your DAC anymore.
We try. The biggest problem with the original Bifrost’s platform is that it frequently had to come back to us for updates. We wanted to eliminate this problem—entirely—with the new version.
In some ways, it actually measures better than a Yggdrasil…so if you’re judging based just on measurements, then it’s probably better. But measurements don’t tell the whole story. If you want great measurements, there’s Modi 3—that’ll save you half a thousand dollars on this guy. But now that you mention it, Bifrost 2 is pretty much a desktop Yggy—it has balanced outputs, it uses DACs from the same family, it has a similar digital filter. And it even has a remote control. No, wait. That’s better than Yggdrasil.
WARRANTY
5 Year Warranty
Don't sweat it, this Schiit Bifrost 2 comes with a 5 year warranty from Schiit that covers manufacturing defects. All products featured on Headphone Zone are backed by an original manufacturer's warranty.
The story of Schiit Audio begins with two veteran audiophiles Jason Stoddard, formerly of Sumo, and Mike Moffat, formerly of Theta coming together to shake things up a bit. Both of them have extensive experience in developing lots of audio and A/V products including the Andromeda III, Cobalt 307, DS Pre and Angstrom 200. From power amplifiers, I/V conversion stages, D/A converters, relay-switched stepped attenuator volume controls in preamps to developing the first DTS home theatre surround processor on the market, Schiit Audio has developed a lot of audio products over the years.
Getting into Designing Headphones
Headphones are the need of the hour everyone who likes music uses a headphone. Therefore Schiit Audio moved to develop personal audio equipment while continuing to design a speaker-based system which includes the industry-leading preamps, amps and DACs. So right now Schiit Audio has a plethora of audio products ranging from personal audio to speaker-based systems. Schiit designs affordable audio products that bring happiness in your lives.
True Multibit DACs and Unique Digital Filter
Unlike ordinary DACs that use delta-sigma, NOS (new old stock) D/A chips, multibit chips, high-cost R2R ladders, Schiit uses unique DSP-based closed-form digital filter which improves the sonic performance of the multibit DAC. Therefore the Schiit's multibit technology brings all of it together using the current-production, medical/military grade D/A converters.
Innovation in Analog
Schiit has opted for an innovative approach for the analog side as well. Even the most affordable Schiit headphone amplifier is a miniature, fully discrete, DC coupled, current-feedback power amplifier. Schiit is credited for introducing Continuity output stage to solve the issue of transconductance droop which was common in Class AB amplifier design. Schiit has also developed balanced topologies like Nexus in Ragnarok 2 and a perfect combination of tube and solid-state with Coherence in Lyr 3.
Designed with High-End Materials for Durability
All the Schiit products are designed for solidity and durability. Even the smallest of the products are made of aluminium and steel while the larger products are made of high-end C core transformers, power supply filtering and low-noise control. All the products have to go through severe testing procedures including the latest APx555 audio analyzer and Avermetrics analyzers. Every product from Asgard and up goes through burn-in to address the issues faced during the initial period of usage. Schiit takes care of all the service and support requirements so that you can concentrate on great sound.
Handcrafted in the USA
Schiit believes that local control of all the aspects of production improves the delivering of the product. Therefore all the Schiit products are designed and made in the USA and most of the cost of the components are going to the US-based companies. Assembled in the USA means that Schiit's chassis guys are from San Fernando Valley, Schiit transformers are made in California, Schiit boards come from the east coast of the USA and all the designing, assembling and testing of Schiit products happen in Valencia, California.
