Vancouver, BC – Hafler (a division of Radial Engineering Ltd.) is pleased to announce the HA75 Tube Head™ headphone amplifier is nominated for the upcoming 31st Annual NAMM Technical Excellence & Creativity Awards under the category of Amplification Hardware – Studio and Sound Reinforcement.
Radial President Peter Janis: “Since acquiring the Hafler brand in 2014, we’ve been developing a new generation of ‘vintage inspired’ products to introduce to the market and it’s a special honor to have one of the first of these products up for this prestigious award. The HA75 comes out at just the right time with just about everyone employing headphones to work on their mix. It’s a 12AX7 tube headphone amplifier with natural warmth and pleasing second order harmonics for hours of use without fatigue. It’s ideal for late night mixing. It also features a unique focus control that replicates listening to loudspeakers in a room.”
“We’ve had reports back from several engineers that have integrated the HA75 into their work flow: Dave Stewart (The Eurythmics), Alan Parsons (Beatles, Pink Floyd), Chuck Ainlay (Mark Knopfler), Jimmy Douglass (Pharrell Williams) and Dave Rideau (Janet Jackson) are just a few who are working with the HA75. It has also struck a chord with some of the top mastering engineers including Eric Boulanger (Imagine Dragons), and Tom Coyne (Adele).”
Proudly made in North America, the Hafler HA75 has been meticulously designed to produce Hafler’s legendary sound quality with sufficient gain to power any type of headphone. The design begins with a heavy steel casing to shield the low level signals from external magnetic fields and RF contamination. A black anodized aluminum front panel adds esthetic appeal. A choice of balanced nickel-silver XLRs and unbalanced gold-plated RCA inputs are employed that will not tarnish over time. Inside, a class-A head-amp combines with a 12AX7 tube stage to power the headphones. This employs a unique non-radiating charge pump that applies 140 volts to the tube to maximize headroom and delivers the character and warmth that so many listeners prefer over solid state counterparts. The output is further optimized to handle all types of headphone impedances from 8 Ohms to 400 Ohms. The HA75 delivers the warmth and character that has made the Hafler pedigree one of the most revered in the history of high fidelity listening.
