Topping A70 Pro Balanced Headphone Amplifier

All New T'ang-ku-la Amplifier Module

T'ang-ku-la translates to 'a mountain that an eagle cannot fly over', the source of the Yangtze River. It symbolizes our spirit of climbing the peak of ultimate performance. This module uses a new three-stage feedback circuit. Further reducing noise and high frequency distortion, making the dynamic range rise to an unmatched 147dB. The new technology greatly reduces heat generation, thus greatly improving reliability, extending electronic component life, and reducing thermal noise.

Re-optimized New Circuit Architecture
Newly developed ultra-noise input stage further improved the noise performance of balanced input and increased the input impedance to 20kΩ thus having better compatibility with incoming devices.

Ground Loop Noise Disappearing Magic
When multiple devices are used in combination, ground loop noise may be encountered. A70 Pro adds a GND/LIFT switch, when ground loop noise is encountered switched to LIFT and the noise will disappear.

Aurora UI Brings A New Experience
Full color screen and three touch buttons bring a changed experience. Display of playback information, FFT or VU meters can be switched according to your requirements.

Relay Volume Control
A70 Pro uses relays and resistor networks to form R2R volume control module, which providing precise volume control, long service life, and will not deviate even at low volume.
