Asgard 2 is the next generation of one of the most popular headphone amps in the world, boasting higher performance and convenience features such as switchable gain and preamp outputs. It’s a versatile control center for your desktop system, ideal for most headphones from IEMs to orthos, and with pre outs for powered desktop speakers.

Significantly Improved Performance

We used what we learned in Mjolnir to significantly improve Asgard 2’s performance. A high-voltage, cascoded JFET gain stage feeds a high-current Class A MOSFET output section. The 80V rails on the gain stage allow us to reduce distortion, while retaining Asgard’s no-overall-feedback design in high-gain mode.

Additional Versatility: From IEMs to Orthos to Active Monitors

Asgard 2 offers two gain settings. The low-gain mode is perfect for high-sensitivity IEMs, while the high-gain mode is ideal for most other headphones, up to and including many orthodynamics. In addition, the preamp outputs can easily be connected to powered speakers, for a complete desktop system.

Made in USA

By “made in USA,” we mean made in USA. The vast majority of the total production cost of Asgard 2—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley.

5-Year Warranty

Asgard 2 is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. FIVE. Which is up to 5X that of our competition, if you weren’t so hot at math. Note the marketing weasel-wording “up to.”

Wait. Tube or solid-state? Yes. Not only is Mjolnir 2 the only balanced tube hybrid headphone amp, it introduces our all-new LISST solid-state tube option for a 100% solid-state option. In terms of performance, it is a unique end-game headphone amp fully ready for any headphone, from IEMs to the hardest-to-drive planars.

Choose Tube Hybrid, Solid-State, or Both

Yes, that’s right. You can get Mjolnir 2 as a tube hybrid, or as a pure solid-state amp—or get both, and swap out as you’d like. You can also swap the standard 6BZ7 tubes for anything in the 6DJ8, 6922, ECC88, and 2492 families, to “roll” the sound to your specific preference. Or just opt for the Schiit LISST (Linear, Integral Solid-State Tube) for a 100% solid state amp. 

Power and Control in Abundance

Mjolnir 2 puts out up to 8W/channel into 32 ohms, but is fully ready for high-sensitivity headphones with switchable gain. Use the standard gain of 8 for hard-to-drive headphones, or switch to a gain of 1 for sensitive on-ear models and IEMs. In addition, Mjolnir 2 also offers both balanced and single-ended input, switchable via the front panel. Want more? How about both balanced and single-ended headphone outputs and balanced and single-ended preamp outputs. Mjolnir also makes a great preamp for your power amps or powered monitors.

Pure Balanced, Differential Topology

Mjolnir uses our exclusive, inherently balanced and differential Crossfet topology—the only circlotron-style topology in a headphone amplifier (well, except for Ragnarok.) It’s balanced in and balanced out, with a custom 4-gang RK27 Alps volume pot—providing end-game performance for a mid-level price.

5-Year Warranty

Mjolnir is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. FIVE. Compare that to the competition.

Made in USA—Really

Don’t roll your eyes. When we say, “Made in USA,” that’s exactly what we mean, with no weasel-wording. The vast majority of the total cost of Mjolnir goes to US companies manufacturing in the USA—most of them within easy driving distance from our office.

Ragnarok is the first truly universal amplifier, fully capable of powering everything from IEMs to loudspeakers. With up to 100 watts per channel into 4 ohms, 3 selectable gains, a sophisticated relay-switched stepped attenuator volume control, complete microprocessor management of all operational points, including bias and DC offset, and Schiit’s Crossfet™ circlotron-style output topology, Ragnarok completely befits its name—in Norse legend, Ragnarok was the “end of the world.”

From IEMs to Loudspeakers

Go ahead. Plug in your sensitive headphones and set Ragnarok’s gain to 1. You’ll enjoy a silent background, and the fine control that a 64-step attenuator can provide. Or run it with the most power-hungry orthos you know. With gain set at 20, and 15W RMS into 32 ohms, you’re ready for an amazing performance. Speakers? No problem. With 60W per channel into 8 ohms, Ragnarok delivers amazing performance with most popular speakers.

A Complete Integrated Amp

Ragnarok includes 5 relay-switched inputs—two balanced and three single-ended, as well as balanced and single-ended preamp outputs for use as a preamp. For outputs, both balanced and single-ended outputs are provided for headphones, and balanced speaker terminal outputs for loudspeakers.

Nothing In the Signal Path Except Signal

Ragnarok is an "intelligent" amplifier, using a microprocessor to oversee every aspect of its operation—from quiescent bias, to DC offset, to complete fault protection. It’s also designed so that any major problem mutes all the outputs and reverts the amp to its low-gain, zero volume mode. This means we can dispense with coupling caps and DC servos entirely, for a gain stage that has nothing in the signal path—except for your music.

Made in USA 

By “made in USA,” we mean made in USA. Ragnarok is built to order in Valencia, CA, by our most experienced assemblers, subjected to a rigorous series of both instrumented and listening tests, and burnt in for 100+ hours before being re-tested and shipped. As with all of our products, the vast majority of the total production cost of Ragnarok—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley.

5-Year Warranty

Ragnarok is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. FIVE. Which is up to 5X that of our competition, if you weren’t so hot at math. Note the marketing weasel-wording “up to.”

Go ahead. Do things with Valhalla 2 that you’d never attempt with other OTL tube amps. Run low-impedance headphones. Use IEMs. Valhalla 2 is a complete re-imagining of Valhalla, with improved performance, higher output capability, lower distortion and output impedance. 

Tubes Made Flexible

While most tube OTL amps are really only designed for 300 ohm Senns and 600 ohm Beyers, Valhalla 2 stretches to include headphones that you’d never expect to use with a tube amp. Go ahead. Use it with Grados. Run it with AKGs. Rely on it for many IEMs. You may even like it with high-efficiency planars like LCD-X, LCD-XC, Oppo PM-1 and HE-400. 

A Complete Desktop Preamp

Valhalla 2 also adds two important features: preamp outs and a gain switch. Preamp outs let you connect your powered monitors directly to Valhalla 2, to give them some of what some people call “tube magic.” The gain switch gives you better control of both output level and impedance, for better matching to your headphones. It's easy to build a complete desktop system around the Valhalla.

Not Your Father’s Tube Amp

If you’re expecting syrupy, tubby, euphonically colored tube sound, you’re in for a shock. Valhalla 2 is exceptionally accurate, neutral, and resolving, without being strident or etched. 

Made in USA 

By “made in USA,” we mean made in USA. The vast majority of the total production cost of Valhalla 2—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US.
