Hafler H400-0078 overview

  • 1Description

The Hafler HA75-DAC is a digital-to-analog converter (DAC) and a discrete Class-A tube-driven headphone amplifier designed to produce professional-quality sound with plenty of gain to power any type of headphone, while offering the added excitement and character of a real tube to optimize the listening experience.

The unit connects over USB to digital audio sources such as a laptop computer. The unit's high-resolution circuitry is compatible with files up to 24-bit/192 kHz. What's more, the digital signal is converted to analog and passed through the tube-based circuitry, combining the best of both digital and analog worlds in one powerful and flexible headphone amplifier.

The Class-A amplification circuit utilizes a 12AX7 tube to drive a variety of headphones with impedances from 8 to 400 Ohms. A 140V charge drives the tube to maximize headroom as it delivers the warmth and character so many listeners favor over solid-state designs. The headphone load switch adjusts the output impedance that is presented to your headphones. Settings of 20 to 400 Ohms allow you to match the amplifier to any headphone's internal impedance rating for optimal performance.

Additionally, the HA75-DAC can add excitement for the listener without losing the stereo field via the Focus control, which brings the stereo image to the center, thus replicating the sound and feel of listening to loudspeakers in a typical space. A Vox function warms the tone akin to an old-school loudness control, addressing the Fletcher-Munson curves to deliver equal loudness when listening at low levels. The Vox control can also can be used and create a "boom-box" effect for those that enjoy a more exaggerated response.

Designed with a 14-gauge steel casing, the enclosure helps shield low-level signals from RF contamination and external magnetic fields. The black anodized aluminum front panel provides two 1/4" headphone outputs, a level control knob, a Focus control knob, a 6-way impedance load knob, a 3-way Vox switch, and buttons for power, input select (analog/USB), and focus engagement.

The rear panel offers a variety of connections including a Type-B USB port for connecting to a computer and a selectable pair of XLR or RCA (balanced/unbalanced) inputs. Output connectors include a thru-put pair of RCAs, which pass an unprocessed signal, while a pair of RCA tube outputs add the Tubehead's warm tube character to the signal path between a preamp and power amp or to the inputs of an ADC for recording.

The XLR connectors are made with glass-impregnated nylon and feature extra-large, nickel-silver pin contacts, while the RCA connectors are gold-plated to ensure an optimized signal flow without tarnishing over time. To keep noise to a minimum, the Hafler HA75-DAC is powered by the included ±16V external supply.

Main Features
  • USB input for high-quality digital audio playback
  • 100% discrete class-A audio circuit with 12AX7 tube driver
  • Focus control simulates listening to speakers in open air
  • High output to handle virtually any type of headphone
  • Choice of balanced and unbalanced inputs
  • Thru-put expands system connectivity with RCA outputs of unprocessed signal
  • Tube Out: Tubehead's warm tube character is added to signal for music playback between preamp and amp or for recording
  • Load impedance selector to optimize for any pair of headphones
Inside
  • Tube Drive: Dual triode 12AX7 tube operates in stereo with a B+ voltage that reaches 140 volts to deliver the warm sonic advantages of a tube without excessive distortion
  • 100% Discrete Electronics: Uses full-sized resistors and capacitors that are hand inserted to deliver high audio quality
  • Individual Transistors: No IC chips. Individual transistors are used at each gain stage to minimize negative feedback and eliminate sound-degrading artifacts
  • Durable Switches: High-quality switches and potentiometers employ steel casings and metal shafts for long-term reliability
  • Glass-Filled XLRs: Glass-impregnated nylon XLR connectors are tougher than steel and feature extra-large, nickel-silver pin contacts for positive connection that will not tarnish over the years.
