The Hafler HA75 is a ‘vintage inspired’ headphone amplifier that has been meticulously designed to produce Hafler’s legendary sound quality while adding excitement and character of a real tube circuit to optimize the listening experience.
The design begins with a 14 gauge steel casing to shield the internal workings from external magnetic fields and RF contamination.
Inside, a 100% discrete class-A head-amp combines with a 12AX7 tube drive to power the headphones.
Unique to the HA75 is a negative feedback control. This enables the user to increase or decrease the negative feedback to produce either a more ‘clinical’ (solid state) or a ‘warmer’ (tube) response
To simulate the response of listening to loudspeakers in an acoustic space, a Focus control may be engaged that brings the stereo image to the center via a fully variable potentiometer.
The HA75 isn’t just an ordinary amp. It has not one, but two – maybe even three – killer selling points, ones that mark it out as something truly special, and also offer something we haven’t seen in others of its kind.
