Schiit Valhalla 3 Unleashed: Thor’s Class A OTL Tube Amp for Mortals Who Dare Drive Hard-to-Tame Headphones

Schiit Audio just dropped the Valhalla 3—a pure triode, OTL/OCL, Class A headphone amp and preamp that’s ready to take on your hard-to-drive cans like it’s storming the gates of Asgard. Priced at $499, it’s not cheap, but for what it does, Odin himself might call it a bargain.

This isn’t just a tweak of the Valhalla 2, Schiit’s longest-serving amp. According to Jason Stoddard, Schiit’s Co-Founder and resident god of audio war, the Valhalla 3 is “completely different,” borrowing its battle-tested tech from the limited-run Folkvangr—aka the giant, tube-filled beast that made headphone nerds cry tears of joy and wallet pain.

Like Folkvangr, the Schiit Valhalla 3 operates as a OTL/OCL design—no output transformers, no capacitors in the signal path. Translation: your headphones are getting raw tube power straight from the source. No filters, no frills, no fluff—just Mjölnir to the ears.

There’s also a switchable impedance multiplier, which sounds fancy but basically means your 32-ohm, stubborn-as-hell planar headphones will finally behave. And unlike the usual high-current buffer cheats, this keeps your cans connected directly to the tubes—like the gods intended.

Valhalla 3 isn’t just a mini Folkvangr—it goes one better. It adds three gain levels, including a zero-feedback setting that unleashes the full fury for high-impedance headphones. It’s like flipping the Bifrost on your gear.

The burning rainbow bridge that spans between Midgard and Asgard, the realm of the gods — not the $800 DAC from Schiit… though, the second option might be a bit more preferable when explaining things to your home insurance company.

Protection? Oh, it’s got it. Not the kind you’re thinking of, though — this is the actual kind that keeps your gear from frying, not the “I’ll-be-back-before-midnight” kind.

Delayed startup, fast shutdown, and analog-style DC sensing keep your gear safe from Ragnarok. Add a filtered preamp output, and Valhalla 3 can anchor your entire desktop system—headphones, active speakers, the works.

A new thermal tray design not only keeps things cool, it also finally makes a Schiit amp look as badass as it sounds. And like all Schiit gear, it’s made in the USA using real metalwork, not some glorified hunk of milled aluminum that costs more to carve than it does to design.

But How Does All of this Norse Magic Work? (For the Head-Fi Nerds…with appreciation to our friends at Schiit)

Glad you asked. Valhalla 3 may look like something Odin would use to warm up his headphones, but inside, it’s got more tech than Thor’s hammer.

OTL/OCL Topology: That means no output transformers and no coupling capacitors in the signal path. Your headphones connect directly to the cathodes of the tubes. No middlemen. That’s a big deal in tube land, and it’s only possible thanks to DC servos and a complex, nerd-approved power supply.

Impedance Multiplier: Most tube amps suck with low-impedance headphones. This clever circuit makes the tubes think they’re driving a higher impedance, so they deliver more power without the usual meltdown.

Analog Computer-Style Protection: No microcontrollers. No BS. Just good old analog circuitry that constantly monitors DC levels so your headphones don’t go poof if something goes sideways.

How is the impedance multiplier different from a buffer?

A buffer adds a solid-state stage between the tubes and your headphones. That kills the whole “tube sound” thing. The impedance multiplier keeps the tubes directly in the path — all the gooey tube goodness, but with more muscle. Think of it as a magic hammer that makes your tubes hit harder.

When should I use the impedance multiplier?

If your low-impedance headphones sound weak or distorted, flip the switch. You won’t break anything. Odin’s honor. Call Mike to complain.

Is this just a smaller Folkvangr?

Pretty much. Folkvangr was a $1,800 10-tube beast that made your desk look like a Viking funeral. Valhalla 3 keeps the soul, loses the bulk (and half the price). But wait. What the hell was the Folkvangr?

Glad you asked.

Timing is everything. The Schiit Audio Folkvangr Headphone Amplifier was released when energy costs were at an all-time high and replacement tubes were not exactly inexpensive — not much has changed since 2022.

We liked it. A lot. Go bold or go home. 

Folkvangr was Schiit’s $1,800 mic-drop moment — their most expensive headphone amp to date and a curveball from a company known for making high-end, American-made gear that doesn’t torch your bank account. Only 250 units were made, making it less a product and more a myth. Think of it as Valhalla’s big brother who shows up once, drinks all the mead, and disappears into legend.

Folkvangr wasn’t just Schiit’s most expensive headphone amp — it was a full-on tube-fueled fever dream. The first DC-coupled, output transformerless (OTL) and output capacitorless (OCL) amp from the brand, it packed ten tubes and an 8X impedance multiplier to give low-impedance headphones a fighting chance. Each one idled at 100 watts just to squeeze out a watt or so of output — pure excess, no apologies.

“Folkvangr is completely bonkers,” said Jason Stoddard, Schiit’s co-founder and head of analog. “There’s no other way to put it. There’s no reason for a 10-tube amp that dissipates 100 watts at idle, to produce only about a watt or so at its best. It measures very badly, and it’s not what we’d use for any kind of IEM. But it’s the answer to a question that’s bugged me for years—what do tubes really sound like—and, at least to me, it sounds very good.”

But, like all things that are too cool for this world, it sold out faster than Loki disappearing into another timeline — never to be spoken of again. Much like that next season of Loki… which, let’s be honest, is probably never coming.

Will this drive all headphones?

Almost. Very low impedance headphones might not be ideal. It does handle most headphones just fine — especially high-impedance models. Beyerdynamic and Sennheiser users can stop grinning like little children who were just dropped at Willy Wonka’s factory — be advised children — he’s sorta creepy — in a weird uncle who wants to hang out with your teenage friends kinda way.

But what about IEMs? Low gain works for most. If your IEMs are hypersensitive divas, you might hear a hiss. Blame the tubes, not the folks at Schiit.

Do the preamp outputs go through the tubes?

Yep. Everything gets soaked in tube flavor — even your powered monitors. Volume and gain settings carry over, so if you’re looking for that warm, saturated sound without cranking cans, this gets it done. Think of it as marinating your monitors in a slow-cooked tube stew — just without the calories and annoying 2 hours of scrubbing the pot clean.

Can I turn off the headphone jack when I’m using the preamp outs?

You don’t have to. The amp handles it like a pro. Plug in headphones? Preamp outs go dark. Unplug ’em? Preamp signal flows again. No switches, no drama, no spreadsheet required.

Can I roll tubes?

Of course. It’s basically encouraged. Swap the input tube (6N1P) for the usual suspects — 6DJ8, 6922, E88CC, ECC85, 6BZ7, whatever dusty gold you’ve hoarded. Just keep the heater current under 2.7A unless you enjoy the smell of burning regret.

The Bottom Line

For $499, Valhalla 3 gives you a fully Class-A, OTL/OCL, all-triode headphone amp and preamp that can actually drive real-world headphones — not just a museum exhibit of 600-ohm relics. It’s got modern protection, clever impedance tricks, and enough tube magic to make even your cold, solid-state heart question its life choices. You want specs? They’re here. You want character? It oozes. You want measurements that beat Magni+? Keep walking. But if you want a slice of sonic Valhalla with just enough Loki mischief baked in — this is it.
