Schiit Audio Hel High Power DAC/AMP Review


  • Use it as a great music DAC/amp. 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.
  • You don’t need to be a gamer to appreciate the quality of Hel. Works great for music, conferencing, etc. Designed and Built in California. Product is supplied with a 110 – 120V US power supply suitable for use in the United States, Canada, and Mexico. This power supply will not work in 220 – 240V countries.
