"One Of The Sexiest Amps Around"

The compact EF2A headphone amp from HiFiMan offers a USB input and built in DAC with Burr-Brown PCM2702 chipset for direct connection to your PC. Analog RCA inputs let you plug in a line level source, such as a CD player. A front panel button lets you toggle between inputs.

"This $169 little dude will deliver performance of amps twice the price… and if looks are your thing, you'll certainly be the cool kid with one of the sexiest amps around," reports Unplggd online for March 22, 2010.

The smooth and rich sound quality is thanks to a vacuum tube output stage using two Chinese 6J1 tubes. The outboard power supply contributes to the quiet performance of the circuitry.

"This $169 little dude will deliver performance of amps twice the price once you find that right pair of headphones that match up (we highly recommend the Grado SR-80's, though we've heard the Sennheiser HD580/HD600's are a nice match too). And if looks are your thing, you'll certainly be the cool kid with one of the sexiest amps around."
