Miimall Topping A70 Pro Headphone Amplifier Silver

SKU CH-ENCW-KZFW5

A fully balanced headphone amplifier delivering 17000 mW per channel with relay volume control, a ground-lift switch and colour touchscreen

  • 17000 mW balanced output drives demanding headphones
  • Ultra-low noise input stage with 20 kOhm impedance
  • Ground-lift switch removes ground-loop hum
  • Relay-based R2R volume control for precise steps
  • Full-colour touchscreen shows FFT, VU and playback data

Fully Balanced Headphone Amplifier

The Miimall Topping A70 Pro is a fully balanced headphone amplifier designed for desktop audio systems. It features a re-optimised circuit architecture with an ultra-low noise input stage and 20 kOhm input impedance. A GND/LIFT switch eliminates ground-loop noise when multiple devices are connected. A colour display with touch controls shows playback data, FFT and VU meters.

Who this suits and who it does not

This unit suits listeners who need a high-power desktop amplifier with relay-based volume control and remote operation. It is not for buyers who require integrated digital-to-analogue conversion or wireless streaming. It also does not meet the needs of users seeking a portable or battery-powered device.

17000 milliwatts per channel at 16 ohms

At 16 ohms the amplifier delivers 17000 milliwatts per channel into balanced outputs. The same load yields 6000 milliwatts per channel from single-ended outputs. This output level decides whether the A70 Pro can drive a specific headphone to the desired volume.

Questions about this item

How much power does the A70 Pro deliver into 16 Ohm loads when running all day?

The amplifier provides 6000 mW per channel into 16 Ohm with single‑ended input and output, and up to 17000 mW per channel with balanced input.

What source connections must I already have to use the A70 Pro?

You need a source with either single‑ended or balanced analogue outputs to feed the amplifier’s inputs.

Will the GND/LIFT switch stop ground‑loop hum when I keep my older DAC in the chain?

Yes, setting the switch to LIFT breaks the ground loop between the A70 Pro and legacy gear, removing the hum.
