HIFIMAN EF100 Hybrid Vacuum Tube/USB DAC Headphone Amplifier

The HIFIMAN EF100  Amp and DAC Offer an Incredible Listening Experience

The HIFIMAN EF100 is a powerful hybrid headphone amplifier and integrated amplifier. Housed in its compact chassis lie three independent amplifier sections: a vacuum tube input stage works as a shared preamp, a Class AB headphone amplifier, and a Class T speaker power amplifier. Benefiting from vacuum tube technology, both headphone amplifier and power amplifier sound warm, smooth, detailed and musical. Working as a hybrid headphone amplifier, EF100 can produce a 2w output under a 32 ohm load so it can easily drive many high performance headphones. In addition, EF100 can also serve as a hybrid power amplifier to drive speakers of moderate to high efficiency. In power amplifier mode, the amplifier output line is fully independent from the digital amplifier line used in the headphone amplifier. Driven by front stage’s vacuum tubes, EF100 combines the warmth vacuum tubes are known for with the high efficiency of a digital amplifier. It is the best of both worlds. When EF100 is used as a power amplifier, it can give 4.5 watts per channel so it can drive HIFI speakers of moderate to high efficiency. At last, with its versatile design EF100 can bring music to life from a variety of sources for both headphones and speaker applications.
