T'ang-ku-la Module ▶️The T'ang-ku-la Module uses a new three-stage feedback circuit. Further reducing noise and high frequency distortion, making the dynamic range rise to an unmatched 147dB new realm. The new technology greatly reduces heat generation, thus greatly improving reliability, extending electronic component life, and reducing thermal noise. 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 switch to LIFT and the noise will disappear. Relay volume control ▶️ A70 Pro uses relays and resistor networks to form R2R volume

Improved NFCA: L30 II uses redesigned NFCA (Nested Feedback Composite Amplifier) module. It provides 2x output power at 300Ω load compared to L30. The new circuit has 0.3uV ultra low noise and 144dB dynamic range as well as 0.00006% THD+N. Sound quality is never a problem: With the help of NFCA, L30 II easily reach the top of the industry, and it has almost perfect performance regardless of distortion, dynamic range, and multi-tone testing. Three gain settings to suit different needs: L30 II has three gain options: -14dB, 0dB, 16.5dB. Improved gain settings can cover a wider range of needs to meet the needs of different headphones from low-sensitivity full-sized over-ears to
