Hafler Launches Two Headphone Amplifiers at AES

Hafler is showing the new HA15 Solid-State and the HA75 Tube Head headphone amplifiers at AES in Los Angeles.

Hafler, owned by Radial Engineering, said the HA15 is a compact solid-state unit while the HA75 is a valve/tube design. Both devices provide serious audiophiles a superior headphone amplifier that will not introduce ear fatigue even after hours of listening.

The company said before the new amplifiers were released they were tested by some of the top golden ears in the audio business. “The response from these industry giants has been nothing short of magnificent,” said Peter Janis, Hafler’s CEO. “With such a wide-level of adoption from the top tier (engineers), you can rest assured that the sound reproduction will address the needs of the most demanding users.”

The HA15 is a 100 percent discrete audio headphone amplifier that has plenty of drive to handle any headphone impedance. The discrete architecture assures minimal phase-degrading negative feedback for a more natural rendering. Both RCA and XLR connectors are offered for connectivity to Hi-Fi and professional recording systems.

The front panel features a traditional level control along with dual headphone outputs for sharing. A FOCUS control introduces a matrix that allows the user to simulate listening to speakers in a room. The matrix mixes the left and right together and lets the listener decide how much of each channel is desired in the ears.

The HA75 Tube Head is a 12AX7 tube headphone amplifier with the character and sonic landscape that is only possible with a tube. The design applies 140 volts to the tube to provide sufficient voltage for a clean sound, yet at a lower scale in order to impart a tube character and harmonic generation.

When pushed hard, tubes introduce a form of natural compression to the signal that do not distort in a square wave but more gradually saturate with even order harmonic distortion. This results in a more pleasing tone with far less ear fatigue when listening to music for extended periods.

The HA75 is also equipped with FOCUS control to simulate listening to live speakers. It has dual headphone outputs with RCA and XLRs input connectors to adapt to either audiophile or recording system setups.

A dual RCA line output on the rear panel allows the user to capture the HA75's tube character and incorporate it into a solid state system. This warms the often sterile tone of a digital recording, bringing warm tube harmonics into play.

The HA15 is priced at $449.99 and the and HA75 is priced at $999.99. Both models are currently shipping.
