If you want the ultimate in a transportable gaming DAC/amp, you’re looking at Hel. Yes, Hel. As in the Norse underworld. That’s why it’s black and red. Or something like that. In any case, Hel delivers like 40x the power of a typical computer headphone output, plus it has a podcast-quality stereo-compatible electret mic input. It’s also an amazing DAC/amp for music, and with a separate analog input, preamp output, and gain switch, it’s ready for all your desktop needs.

Power and Quality to Spare
Hel delivers a full 1000mW into 32 ohms—enough to light up any gaming headphone you throw at it, and tons of power for virtually every audiophile headphone, too. With an all-new, DC-coupled, high-current output stage with feedforward, its performance is far beyond any computer or phone. In addition, the microphone input uses a stereo 24-bit AKM ADC with front-panel gain control for highest possible quality.
Use it as a great music DAC/amp. You don’t need to be a gamer to appreciate the quality of Hel. Use the front-panel gain switch to cover virtually every headphone need, from sensitive IEMs to low-efficiency planars.
Use it as a DAC/preamp. Connect to powered monitors or speaker amps using the variable outputs on the back.
Use it as an amp. Connect your phone (or any other analog source) to the convenient rear jack, and switch with a front-panel control.
Use it with phones, tablets, or computers with low-powered USB ports. Hel reports as a 0mA device. We’ve included a second USB port for power input and a 2.1A USB power supply.
Like DACs costing many times its price, Hel uses the AKM AK4490 D/A converter. Coupled with an Alps RK09 potentiometer, high-quality filter and amp stages from Texas Instruments, a sophisticated bipolar +/-12V supply, and precision thin-film resistors and film capacitors, Hel delivers amazing performance for its price.
