產品介紹

DAC/Amps: They’re Sooooo Last Decade
Don’t get stuck with dumpster fodder 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 DAC or 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 gigadollar 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 DAC, phono, or input module:
AK4490 DAC Module. Jotunheim’s 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 DAC. 
MM 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.
