From Schiit
Do you have Raal/Requisite headphones? Do you want to ditch the speaker amp and interface box for something smaller and simpler? Do you want a true one-box solution you can carry with you wherever you go? Then you want Jotunheim R—the only direct-drive ribbon headphone amp on the planet.

Designed Especially for Raal/Requisite Headphones
Let’s be clear. If you have other kinds of headphones, this amp isn’t for you. This amp was designed for one kind of headphones only: the Raal/Requisite ribbon headphones. Delivering up to 13A (amps…yes, amps) per channel into the Raal’s extremely low impedance load, and including the baffle compensation needed for the SR1a, the Jotunheim R is completely unique. It means you can leave your speaker amp behind, forget the Raal/Requisite interface box, and, if you buy it with the optional True Multibit™ DAC, you have a one-box system that’s easily transportable.

Configure To Your Needs
Select Jotunheim R as “just an amp,” or add an internal or external DAC to tailor the system to your needs.

  • No DAC. If you already have a DAC, or don’t need one, choose Jotunheim R without a DAC module or external DAC, for $799.
  • True Multibit DAC module (internal). Choose the optional Multibit DAC Module to get Schiit’s unique digital filter and multibit DAC architecture, for $200 more.

Flexibility and Convenience
Jotunheim R provides switchable baffle compensation, to ensure compatibility with future ribbon headphone models, as well as switchable passive preamp outputs, and both balanced and single-ended inputs. No power bricks or external power supplies are required; it plugs straight into the wall for maximum convenience.

Unique Nexus™ Discrete Gain Stage with Ultra-High-Current Output
Jotunheim uses our unique Nexus™ gain stage that debuted on the flagship Ragnarok 2 integrated amplifier. This inherently balanced, differential, current feedback topology accepts both balanced and single-ended input without the need for splitters and summers.

Designed and Built in California
By “designed and built in California" this is what we mean: the vast majority of the total production cost of Jotunheim—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. Our transformers are also made in California. You get the picture.

5-Year Warranty
Jotunheim R is covered by a 5-year limited warranty that covers parts and labor.
