From HiFiMAN
HiFiMAN has announced their newest headphone amplifier, the EF100. A versatile hybrid design that combines tube and solid-state technology, the HiFiMAN EF100 is a moderately priced amplifier that will drive the majority of high-performance headphones, as well as efficient loudspeakers. The EF100 has an MSRP of $499 and is available for immediate delivery. 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, the EF100 can produce a 2w output under a 32-ohm load so it can easily drive many high performance headphones. In addition, the 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.

Key Features of the HiFiMAN EF100:
• Hybrid amplifier design utilizing both tube and solid-state performance
• Dual purpose--can be used to drive headphones or speakers
• Stable under a variety of loads
• Will accept multiple sources
