    If you’re talking fully discrete, truly balanced headphone amps, you’re usually talking big, big money. Not with Jotunheim 2. It meets or even exceeds the insane parts and build quality of boutique amps. A true balanced, 4-gang, silky-smooth Alps RK27114 potentiometer and 1% “supermatched” JFET inputs, 10% matched, paired BJT gain stage and output devices, and zero capacitors in the signal path is just a start. Jotunheim 2 also features our exclusive Nexus™ current-feedback, inherently differential, input/output agnostic topology. It also includes our Continuity S™ output stage for exceptional linearity and efficiency at high output. Or, in English, Jotunheim 2 connects seamlessly to all your sources without compromise, puts out an incredible amount of power, and is whisper-quiet on even the most sensitive IEMs.

    Total Desktop Control
    Jotunheim 2 provides all the connections and control for your entire desktop. Choose balanced, single-ended, or an internal card source with one front panel switch. Enjoy all your headphones, from the most power-hungry to the most sensitive. Hook up to powered monitors or speaker power amps via the balanced and single-ended preamp outputs. And, enable or disable the preamp outputs with a convenient switch. Jotunheim is all you need for a state-of-the-art desktop.

    Modularity: Tailored To Your Needs, Ready For the Future
    Jotunheim 2 is the only modular, affordable balanced headphone amp available today. This means it’s the only amp that lets you tailor it perfectly to your needs. Choose the optional True Multibit DAC module to get Schiit’s unique time and frequency domain optimized digital filter and multi-bit D/A converter.

    Also, Jotunheim 2’s modular design means you’re ready for the future. You won’t get stuck with dumpster fodder if DAC technology changes just swap the module. And, you won’t get stuck with an amp that doesn’t work for you.
