An extraordinary headphone amplifier from Red Wine Audio

Red Wine Audio makes some of my all-time favorite headphone amplifiers, but they're pretty expensive. The Isabellina HPA LFP-V Edition, for example, runs $2,500; it was designed and built in Vinnie Rossi's small factory in Durham, Conn. The Isabellina is more than just a headphone amp, it features a spectacularly good digital-to-analog converter and a hybrid transistor/vacuum tube audio amplifier. While the amp can be run off an AC power outlet, it sounds best powered by its built-in 25.6 volt Lithium Iron Phosphate battery pack. The battery can play for up to 10 hours, and … Read more

Schiit's muscular Lyr headphone amplifier

I've written about Schiit's amazing headphone amps before, but their new Lyr is the company's first high-output headphone amplifier. It delivers up to 6 watts into 32 ohm headphones. If that sounds like overkill for most headphones I'd agree, but there are a few headphones that need more power to sound their best. That's where the Schiit Lyr ($449) comes into its own.

JH Audio JH-3A: The $1,748 earbud

Sound-quality advances in headphone design show no sign of slowing down, and even old names like Philips and Sony are getting serious about making great-sounding headphones. Sadly, those brands aren't attempting to make anything that could be compared with the world's best, like the JH-3A headphone/amplifier system, from JH Audio.

That company's founder and designer, Jerry Harvey, started building in-ear monitors for rock bands in 1995. He counts Lady Gaga, Alicia Keys, Aerosmith, Foreigner, and Linkin Park as customers. Harvey is currently with the Van Halen tour--the band uses his 'phones onstage--and Harvey uses their feedback to improve his designs.

The JH-3A is an amplifier/in-ear headphone system, with analog and digital inputs with up to 24-bit resolution and 96kHz sampling rates. I've used portable headphone amplifiers before, and they can sound great with all types of headphones, but the JH-3A takes in-ear headphone performance to another level.… Read more
