Product : Jotunheim

You've been asking for a one-box, do-all, no-excuses desktop system that is ready for any headphone and powered monitor on the planet. We think we have it. At the same time, why don't we make this whole combined DAC/amp  idea seem really outdated? Done and done. Welcome to Jotunheim!

DAC/Amps:

Don't get stuck when DAC technology changes,choose Jotunheim and be ready for today, and the future. Configure Jotunheim to your needs: use it as just an amp, or add an internal USB DAC or Moving Magnet phono preamp. In the future, you'll be able to easily upgrade to a different module,maybe even something beyond a DAC or phono preamp.

Ready For Any Headphone

IEMs? Sure. HE-6? Sure. If this means nothing to you, just be confident that you can plug any headphone into Jotunheim and get great sound, with ultimate power and authority. Balanced or single-ended,it doesn't matter. With 5W output into 32 ohms from the balanced outputs, Jotunheim has tons of power to spare.

Ready for Any Powered Monitor or Power Amp

Balanced and single-ended preamp outs mean that Jotunheim is ready for any powered desktop monitor,or to plug into those expensive monoblocks you've been eyeing.

Unrivaled Flexibility

Select high or low gain with the flick of a front-panel switch, for compatibility with both easy-to-drive and hard-to-drive headphones. Select balanced input, single-ended input, and an optional USB DAC, MM phono, or input module:

AK4490 DAC Module. Jotunheims optional DAC module uses two AK4490 DACs in a hardware-balanced configuration, with a passive-filtered output stage and asynchronous USB Gen 2 input. Add it to Jotunheim for a true best of both worlds amp and USB DAC.

Moving Magnet Phono Input Module. Or, choose the optional MM phono input module, for 42dB of gain and exceptional low-noise performance from a phono stage with fully passive RIAA, for great phono sound right on your desk.

Made in USA.

3 Year Warranty

Jotunheim is covered by a 3-year limited warranty that covers parts and labour.
