Hafler HA75-DAC headphone amplifier: Valves from Vancouver

Posted on 26th September 2017

The HA75-DAC, valve-based headphone amplifier and USB digital to analog converter (up to 24bit/192kHz) is based around the 12AX7 valve

A non-radiating charge pump is utilised to apply 140V to the valve for, “…optimal headroom and vintage inspired warmth,” said the company.

Also included is the Focus control, which can be dialed in to simulate the, “…effect of listening to live speakers in a room.”

Another new feature on the Class A HA75-DAC is the headphone load impedance selector. This can be set from 20 to 400 Ohms. You’ll also find a 3-position “voicing” switch that can be used to boost low frequencies, increase overall loudness or set to bypass for “neutral voicing”.

The HA75-DAC features both XLR and RCA analog audio connections. Spanning 165 x 200 x 44mm, the price is $1,300

I’ve had the HA75 for 6 months now. Make my 702’s really shine. The first sent to me was an out of box failure. My dealer got a new replacement for me. I tried to do that,but the worst importer in audio refused, and got really snotty with me.They wanted me to return it for repair, and cover all shipping costs . I’m never going to purchase anything from Hafler again. Arrogant nonlisteners.
