The Onkyo HA-70 is a compact desktop headphone amplifier with a built-in DAC, introduced as part of the Japanese brand’s 80th anniversary. With a fully balanced signal path, two ESS SABRE DAC chips and three gain settings, Onkyo positions the HA-70 as the centrepiece of a premium personal hi-fi system, for everything from sensitive in-ear monitors to demanding high-impedance headphones.
Onkyo HA-70: fully balanced from DAC to output
According to Onkyo, the HA-70 uses a fully balanced signal path from the digital-to-analogue conversion all the way to the headphone outputs, with dedicated DACs and amplifier stages for each channel. The company says this improves channel separation, lowers noise and distortion and adds dynamic stability.
The conversion is handled by two ESS ES9039Q2M SABRE DAC chips. On the digital side, an XMOS XU316 USB interface accepts PCM up to 768 kHz and DSD256 (via DoP), so the Onkyo HA-70 can play practically any high-resolution file from a computer or streamer.
Why Onkyo is moving to the desktop
Onkyo frames the launch as a response to a changing market. Headphone listening, the company says, has evolved from a convenient alternative to loudspeakers into the preferred way of listening for many music lovers, and that raises the bar for desktop components. The Onkyo HA-70 is meant to answer that demand with the engineering and craftsmanship the brand built up over eight decades of home hi-fi. In other words, this is not a gadget add-on to a receiver, but a dedicated component that Onkyo wants listeners to judge on the same terms as its full-size amplifiers.
Three gain stages for every headphone
Onkyo designed the HA-70 to drive headphones up to 600 ohms. Three gain settings cover the range: Ultra Low Gain for IEMs, Low Gain for low-impedance headphones and High Gain for hard-to-drive reference models. On the front panel, small indicator lights next to the large central volume control show the selected input and gain setting.
Compact aluminium chassis with plenty of inputs
The Onkyo HA-70 measures just 180 x 141 x 46 mm (W x D x H) and is housed in a precision-machined aluminium chassis with a tinted top panel. Connectivity includes USB-C, optical and coaxial digital inputs, RCA connections and balanced XLR outputs. Onkyo says this flexibility lets the Onkyo HA-70 slot into a wide variety of desktop and personal hi-fi systems.
The timing is no coincidence. Sister brand Klipsch names the HA-70 as an ideal partner for its new Stratos HP-2 and HP-3 headphones. Earlier this year Onkyo also celebrated its anniversary with the MUSE Y-50 and Creator Series.
Pricing and availability
The Onkyo HA-70 will be available in spring 2027. The suggested US retail price is $649.99. European pricing has not been announced yet. More information is available on the Onkyo website.
