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.
- 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.
- Bifrost 2 DAC (external). Or choose the all-new, modular Bifrost 2 DAC for even higher performance, for $600 more.
So I have these Audeze headphones—
BZZT! Stop right there. Nope. This amp is only for Raal/Requisite headphones.
- Jotunheim R is the only direct-drive ribbon headphone amp in the world. As in, you connect the headphones to the amp and you’re done. This substantially simplifies the system.
- Jotunheim R means you don’t need a speaker amp to run the Raal/Requisite headphones. Nor do you need their speaker amp interface box. As stated above, it’s one and done.
- Jotunheim R can be configured with an internal DAC, which makes it a one-box transportable system for driving the Raal/Requisite headphones.
"Schiit’s new Jotunheim R is an excellent, and extremely high-value, way to drive the RAAL-requisite SR1a. Indeed, when it comes down to it, the pairing of Jotunheim R and SR1a outperforms every conventional headphone/amplifier combination I have heard - irrespective of price. You absolutely get the full-fat SR1a experience here, with no muting or blunting and no excuses nor caveats needed.
"Interestingly, the Jotunheim R rendered these well-recorded live tracks with more there-ness and deeper bass than the Pass Labs amplifier did. Compared to the Jot-R, the XA25 might be considered a little too light and airy.
