TOPPING A70 Pro Fully Balanced Headphone Amplifier

T'ang-ku-la Module: Soaring Performance 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. Re-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: Disappearing Magic 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 noi
