Product Feature
Designed by Shiit Audio, for RAAL-requisite headphones. 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 RAAL’s extremely low impedance load, and including the baffle compensation needed for the SR1a. It means you can leave your speaker amp behind, forget the RAAL-requisite interface box, and, if you buy it with the optional True MultibitTM DAC, you have a one-box system that’s easily transportable.

The World’s First Earfield Headphone Monitor.
The SR1a by RAAL-requisite is the world’s first Earfield™ headphone monitor. Experience mixing, mastering, and home listening with unparalleled accuracy and realism in a sound field devoid of room acoustics and comb-filtering caused by work surface reflections. Earfield™ technology delivers unheard-of program accuracy and a speaker-like sound field experience.
True Ribbons For a Reason.
The SR1a is also, the world’s first True-Ribbon™ headphones. Highly specialized ribbon drivers were developed that reproduce 30Hz to 30kHz bandwidth in order to eliminate the need for sealed chambered bass and allow for open-air baffles (both front and back) for a true full-frequency sound field.
SR1a Freedom.
Professional engineers report that SR1a Earfield Monitors™ reveal more detail and accuracy than even their finest traditional studio monitors or headphones. Helping to achieve high-quality, transferable mixed results in non-traditional environments. The accuracy, musicality and portability of the SR1a free the engineer to work whenever, and wherever they choose.
Superior Comfort.
Unlike standard headphones whose weight and heat create listener discomfort over time. The SR1a Earfield™ design eliminates heat buildup on the ears providing a cool, natural airflow. Your ears will appreciate the complete absence of sound pressure against the eardrums caused by traditional sealed can designs. SR1a headphones can be worn comfortably for hours at any listening level.
Fine materials. Hand-built.
The SR1a features; carbon fibre baffles, stainless spring steel headband, aluminium ribbon drivers, plush memory foam bars, and lambskin leather. Every SR1a is expertly handmade, in Serbia, by the skilled European craftspeople who build world-renowned RAAL ribbon tweeters.
Direct-Drive Ribbon Headphone Amplification.
Leave your speaker amp behind and forget the RAAL-requisite interface box with a ribbon headphone amplifier.
Direct-Drive Amplifier for RAAL-requisite True-Ribbon Headphones.
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—a direct-drive ribbon headphone amplifier.
With DAC. Without DAC.
Get Jotunheim R as “just an amp,” or add an internal DAC to tailor the system to your needs. If you already have a DAC, or don’t need one, choose Jotunheim R without a DAC module for £799. Choose the optional DAC Module to get unique digital filtering and multibit DAC architecture, for £200 more.
