Newark DE, November 18 2014 -– HiFiMAN, a leading designer/manufacturer of high performance headphones, amplifiers and portable audio products, announced their newest headphone amplifier, the EF100.

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. Benefitting 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.

According to Dr. Fang Bian, Founder and President of HiFiMAN, “Driven by the front stage’s vacuum tubes, EF100 combines the warmth vacuum tubes are known for with the efficiency of a digital amplifier. It is the best of both worlds. When EF100 is used as a power amplifier, it can deliver 9 watts total so it can drive many good quality speakers. At last, with its versatile design EF100 can bring to life music from a variety of sources for both headphones and speaker applications.”
