An audiophile tube-based Tube Head™ headphone amplifier and USB digital-to-analog converter, the Hafler HA75-DAC comes with a number of useful and innovative features—blending superior engineering with powerful user-controlled features that excite and enhance the listening experience.

This amplifier's uncompromising design builds upon the original HA-75's foundation, a design that has received praise from many of the recording industry's 'golden ears' for its incredible clarity, warmth, and character, courtesy of its tube-based topology. This same circuitry and 12AX7 tube is incorporated within the HA75-DAC, along with the addition of a USB input for monitoring high-fidelity digital audio up to 192 kHz. RCA and balanced XLR connectors provide analog inputs, and a selector switch on the front of the HA75-DAC lets you easily switch between analog and digital sources.

A number of additional features give you the ability to tailor the performance of the HA75-DAC to suit both your listening style and your headphones. Its Focus control simulates the experience of listening to speakers in a room, using an active matrix that can be dialed in according to taste. A 3-position voicing switch lets you adapt to the balance of your headphones or the source material by applying a loudness curve or enhancing the bass response; the voicing circuit can also be bypassed for a neutral response. Another exciting addition is the load selector switch, with which you can tailor the output impedance to match any pair of headphones available.

Its chassis is built from 14-gauge steel to block stray magnetic interference, and the back panel features gold-plated RCA connectors to ensure optimal signal transfer. Additional 'thru' and 'tube out' RCA outputs let you use the HA75-DAC to feed another input device, or connect between a preamp and power amp to impart the character of the 12AX7 tube.
