"The HA-1A may be the best thing that's ever happened to headphones...champagne sound for beer-budget bucks."

– Sam Tellig, Stereophile, June 2006

"Pardon me, but that grasp you might have heard was me catching my breath and gathering my wits after unpacking the Cayin HA-1A headphone amplifier. Actually, make that 'vacuum tube integrated headphone amplifier.' A jewel box of a beauty, the Cayin is for the dedicated headphone aficionado – the pleasure-seeking hobbyist who prizes Mount Blanc pens, Panerai wristwatches, or cases of Antinori Solaia 1997." – Neil Gader, The Absolute Sound, January 2008

The Cayin HA-1A is a fully adjustable high quality audiophile tube Headphone Amplifier.

This is one seriously heavy-duty piece of gear. We're not kidding. It weighs 15 ½ pounds!! It's made from ultra-high-quality parts. It looks stunning – especially for a headphone amp. The sound is so typically Cayin – that being natural and musically delicate without excessive warmth or detail. In other words: just right. It's got an impedance selector switch that ranges from 6 to 300 ohms, so that it interfaces perfectly with any pair of headphones.

And, with an efficient pair of bookshelf speakers, the HA-1A can actually serve as a very effective integrated amp. How's that for versatility?

We dare you to find a head amp for under $1,000 that's even in the same league as this! Seriously!

Check out what Sam Tellig from Stereophile had to say:

"…If you've been driving a pair of quality headphones from the headphone jack of a preamp or integrated amp – or even if you already own a standalone headphone amp – the HA-1A may come as a revelation. How good can your present headphones sound? Probably very good indeed. So good that you might stop listening to your loudspeakers…The HA-1A breathes life and light into music in a way that transistors – and many tube amps – simply cannot. It makes musicians sound here, not there…The HA-1A has a way of making headphones sound less like cans (British slang for headphones) that is downright…uncanny. And the HA-1A did bass – rich, full, tuneful, tight bass. I've always thought my Sennheiser HD 600s sounded a little thin and bass-shy. Such is not the case. The HA-1A may be the best thing that's ever happened to headphones…champagne sound for beer-budget bucks." – Sam Tellig, Stereophile, June 2006

"I would have spent $750 if that's all it did was a preamp. Easily! I was blown away. It's got that full, rich tube sound, but it's still very transparent. I love it. It sounds fantastic; that big-boned tube sound. This is an extremely good piece." – Harbert Ringo, Acoustic Sounds customer using the Cayin HA-1A as a preamplifier
