Prepare to be enchanted by the Cayin HA-1A MK2, a beautifully designed and expertly crafted masterpiece that's more than just a headphone amplifier. It's a work of art that delivers a warm, musical tone, perfectly complementing its unique appearance.

**A Legacy of Excellence**

**Versatile Connectivity**

Connectivity is a breeze with two-source preamp functionality, allowing you to link two analogue sources (labeled as AUX and CD) via RCA connections.

**Tailored Listening Experience**

The HA-1A MK2 offers not one, but two Neutrik 6.35mm stereo headphone outputs on the front panel. Each output has its unique character—Output A delivers a dynamic and energetic sound, while Output B offers a softer, laid-back feel.

**Precision Sound Customization**

With selectable settings for output impedance (32, 64, 150, 300, or 600 ohms), this amplifier ensures precise matching with a wide range of headphones available in the market. You have the power to customize your sound by choosing the ideal headphone output and impedance level, perfectly aligning with your headphones and listening preferences.

**Beyond Headphones**

But that's not all—the HA-1A MK2 isn't limited to headphones. It features a pre-out connection, enabling it to function as a tube preamp when paired with active speakers or a power amplifier, expanding its versatility and making it an even more valuable addition to your audio setup.
