Bring back big—power, that is! At 200W stereo into 8 ohms and 400W into 4 ohms, the all-new Wotan will drive virtually anything. And, at the same time, it’s the most advanced amp we’ve ever built, with true dual-mono design, switchable no overall feedback, intelligent temperature management, and Forkbeard™ control and integration.

Dual Mono. Totally Overbuilt.
Wotan starts with two separate 600VA transformers, for a completely dual mono amplifier design. Add 160,000uf filter capacitance. 24 150W Toshiba output devices, 7 internal power supply rails per channel, and two fans that only kick in when you need them, and you get an insanely capable , designed for driving difficult speakers without breaking a sweat.
 
Nexus™ Differential Topology, Switchable Feedback
Like Tyr, Wotan is a differential Nexus™ amplifier, our unique current-feedback design that is inherently balanced. To this, we added a new trick: switchable feedback. Use the front panel button (or Forkbeard) to turn overall feedback on or off, for better synergy with more systems.
  
Intelligent Oversight, Silent Fans
Wotan includes internal sensors for current, temperature, DC, and other operational parameters. A 32-bit microprocessor manages and protects the amp in case of any fault, for near-bulletproof reliability. Wotan also adds two fans—which normally stay off. When temperatures climb, the fans switch on—slow at first, then building to full speed if necessary. That way, you’ll never hear them over the music.
 
Forkbeard™: System-Wide Control, Visibility, and Optimization
We saved the best for last—Wotan also includes Forkbeard, for system-wide control with a broad range of Schiit products. Forkbeard gives you instantaneous power output readings, system health stats including temperature and current, allows you to switch feedback, change inputs, and trigger Standby mode remotely...and that's just the start.  
  
Designed and Built in the USA
By “designed and built in the USA" this is what we mean: we design our products in Texas and California, and we make our products right here, too. The vast majority of the production cost of Wotan—chassis, boards, transformers, etc—goes to US companies manufacturing in the US. And it all comes together in our San Antonio, Texas facility.  
 
5-Year Warranty and Easy Return Policy
Wotan is covered by a 5-year limited warranty that covers parts and labor. And if you don’t like your Wotan, you can send it back for a refund, minus 5% restocking fee, within 15 days of receiving it.
 
15-Day Satisfaction Guarantee
Try Wotan for 15 days. If you don’t like it, send it back for a refund, minus a 5% transaction fee. Try spending 15 days in an audio store. They’ll kick you out. Unless you buy them donuts. Maybe.

Audio Precision Report for Wotan
 

Fans?
Yes.

I mean, argh, fans!
Yes. But they’re usually off.

What do you mean they’re usually off?
We mean that, at normal volumes into normal loads in normal rooms, the fans are usually off. They only turn on when you crank it, or if you like it 85 degrees F in the house, or if your speakers are insanely difficult to drive, or all of the above.

But! Fans!
You seem to have a problem with the idea of fans. So did we, for many decades. The thing is that fans these days are very reliable, reasonably quiet, and much less expensive than they have ever been. So now they make sense. Times change. Try something new. You might like it!

But what about all the cat hair and brisket smoke that the fans will pull into my amp?
We’d suggest maybe not putting it near pets or patio, but hey, you do you. Seriously, though, there are many ways to manage dust in your listening environment. Or, if you’re 100% totally opposed to fans, then there’s always Tyr, which, since it has twice the total heatsinking, doesn’t need a fan.

Speaking of Tyr, this is rated higher than Tyr into 4 ohms. How does that work?
It works that way because Wotan doesn’t have a huge choke in-between the transformer and the power supply, so it has less power supply losses. Which means it puts out a bit more power than Tyr, especially into 4 ohm loads.

So this is essentially a stereo Tyr?
Essentially. It uses the same transformer as Tyr (but 2 of them), and the same Nexus topology. Wotan, however, is a conventional Class AB output stage design, unlike Tyr’s Continuity™ output stage.

But you added switchable feedback on Wotan, but not Tyr?
Development improves the breed. We tried switchable feedback on the Wotan prototype, we liked it, so it went on the production version.

Doesn’t no feedback monumentally screw up the damping factor?
It doesn’t do it any favors. So if you want high damping factor, you should run Wotan with overall feedback on.

But isn’t a higher damping factor good?
Maybe. Perhaps. Depends on the system. Basically try it both ways, and choose the one you like. There are no prizes here other than your own satisfaction.

Boy you guys are weird.
Yeah, try talking to Tyler about free will and millionaire AIs. Have fun with that.

Okay, moving on. Will this amp drive any speaker I have?
Pretty much anything, yes.

Why can’t I run it mono like a Vidar?
Because it’s already a differential amplifier. Since it’s already differential, both output terminals are driven—there is no “ground.”

But it looks like Vidar puts out more power into 8 ohms when run mono.
Yep, it does. Vidar, however, doesn’t have Wotan’s thermal management; Wotan will be much better for difficult loads than Vidar.

So does this have standby like Vidar?
Absolutely. Press a button on the front panel and Wotan goes to sleep. It only consumes about 1-2 watts in standby, while being ready to run. Or you can select standby from Forkbeard.

Can I run balanced inputs like Tyr?
Yes. Even better than Tyr, actually, since you can switch from balanced XLRs to single-ended RCAs via front-panel switch. Or via Forkbeard.

What does Forkbeard™ do?
Forkbeard does everything a remote control does, but for multiple products in multiple stacks. For a preamp, it controls volume, selects inputs, picks output modes, etc. But it also does a lot more, like show you system health—temperature and instant power on an amp, for example, and tube heater status on a tube preamp. It can do even more when multiple products are brought together, like Visual Volume, an easy way to tell how much headroom you have left in your system. More info is available here: schiit.com/forkbeard

Wait a sec, did you say Instant power? LIKE VU METERS?
Not exactly. These are actual power meters. They show how hard the amp is working. 

WAIT A SEC THAT’S VU METERS!
Not really. They do have a floor, as in a lowest level they can run, based on amp bias. They will vary with speaker load. They are not traditional VU meters, showing what your input level is. But they definitely let you know how hard the amp is working!

HOLY MOLY VU METERS!
You seem very excited. That’s cool.

No Android option?
Not yet. Someday soon.

Hey I do Android development—
Cool, but since we are becoming a software company (by default, by doing these crazy new things with Forkbeard), we need to really become a software company. That means our apps, software, and firmware are done by an in-house team. If you are interested in joining our team, please contact [email protected] and let them know.

Wait a sec, I don’t want no Bluetooth crap on my product!
Cool, then get it without the Forkbeard module. You’ll also save $50.

I’m OK with Bluetooth, but I don’t want to share data with you. What nefarious info are you collecting with your Forkbeard app?
None. Hell, you don’t even have to make an account to use it. No sign in, no info, hell, no pairing—it’s based on a broadcast prototcol so it’s as easy as downloading the app, opening it up, picking the Forkbeard products that show up, adding a passcode (so your butthead neighbor can’t mess with you), and using it.

So this is not a Class D amp?
No.

No switching supplies?
No.

Some of my friends are super into Class D and say it’s the future.
There are plenty of Class D amps out there. Wotan isn’t one of them.

Okay. Fine. Who’s Wotan?
Wotan is another name for Odin in Norse Mythology. He’s basically the biggest baddest god of them all. Which, after you experience Wotan, we think you’ll believe is totally appropriate.
