Description

Founded by Dr. Fang Bian, HiFiMAN today is widely regarded as one of the leading designers and manufacturers of high performance headphones. Their planar magnetic over the ear headphones showcase the kind of sound you would expect from a premium headphone brand.

It's no surprise that a company this dedicated to pure, quality audio offers one of the best, most versatile hybrid headphone/integrated amplifiers you can get for $500. The EF100 packs in the power, containing within its handsome and compact chassis three independent amplifier sections: a vacuum tube input stage that works as a shared preamp, a Class AB headphone amplifier, and a Class T speaker power amplifier.

Use the EF100 to drive your most beloved headphones, producing a 2w output under a 32 ohm load resulting in peak performance. Power your desktop speakers with the EF100 and see what your moderate-high efficiency speakers are truly capable of producing. And in power amplifier mode, it gives 4.5 watts per channel, driving HiFi speakers of moderate to high efficiency. The USB input and digital-to-analog converter make it simple to stream high-quality audio. Driven by front stage's vacuum tubes, the EF100 flexes its hybrid muscle, providing the warm of tubes with the efficiency of a digital amp. It's the best of both worlds.
