And with the added bonus of acting as a preamplifier, the A70 Pro seamlessly adapts to your audio needs. Dive into the world of high-fidelity sound with precision control, customizable settings, and a vibrant Aurora UI—all in one sleek package.

T'ang-ku-la Module

The T'ang-ku-la Module, named after a mountain that an eagle can’t fly over, symbolizes the soaring spirit of this amplifier. This module features a new three-stage feedback circuit that further reduces noise and high-frequency distortion, pushing the dynamic range to an unmatched 147dB. The innovative technology also reduces heat generation, enhancing reliability, extending component life, and lowering thermal noise.

Optimized Circuit Architecture

The A70 Pro boasts a newly developed ultra-low noise input stage that improves the balanced input noise performance and increases input impedance to 20kΩ, ensuring better compatibility with incoming devices. The redesigned gain architecture further diminishes noise and distortion at high gain states compared to its predecessors.

Ground Loop Noise

Say goodbye to ground loop noise with the A70 Pro's GND/LIFT switch. When noise is encountered, simply switch to LIFT mode, and the noise will vanish.

Aurora UI

The A70 Pro boasts a full-color screen and three touch buttons, allowing you to customize the playback information, FFT, and VU according to your preferences. Additional functions are available by pressing the volume knob.

Volume Control

Experience precise volume control with the A70 Pro's relays and resistor networks, forming an R2R volume control module. This ensures long service life and accuracy, even at low volume levels.
