Description
Brand: TOTAUDIO
Color: Black
Characteristics:
- DISCREET NFCA: The Topping A90D features a 39-transistor NFCA amplification stage in a balanced design. The hybrid feedback architecture provides excellent AC and DC performance, allowing the Topping A90 Discrete to benefit from high output power. Ultra-low noise transistors are precisely paired and connected in parallel to ensure extremely low noise and distortion.
- High-voltage device: The Topping A90 Discrete offers high voltage and output current. The former allows the amplifier to easily accompany high-impedance headphones, while the latter provides sufficient power for low-sensitivity headphones.
- Gain settings: With its two gain settings, the Topping A90D is suitable for a wide range of headphones. Combined with a noise level of just 0.2 µVrms, even the most sensitive IEMs are completely noise-free.
- Integrated Preamplifier: In addition to the headphone amplifier section, the A90 Discrete features a preamplifier circuit with 20 Ω unbalanced and 40 Ω balanced outputs, compatible with most amplifiers on the market. Furthermore, both modes can be used simultaneously, and the remote control provides easy access to every function.
- Individual Volume Control: Finally, the A90 Discrete can be controlled via R2R volume using unique relays and resistors. This allows for extremely precise control with perfect channel balance and excellent durability.
- 【Satisfaction Guarantee】As an official Topping dealer, we can guarantee the quality and reliability of our products. We are happy to resolve any questions or concerns quickly and professionally.

Details: NFCA DISCRETE The Topping A90D features an NFCA amplification stage with 39 transistors in a symmetrical design. The hybrid feedback architecture provides excellent DC and AC performance. Thus, the Topping A90 Discrete benefits from high power efficiency. Ultra-low noise transistors are precisely paired and connected in parallel to ensure extremely low noise and distortion. HIGH VOLTAGE DEVICE The Topping A90 Discrete offers high voltage and output current. The former allows the amplifier to easily accompany high impedance headphones, while the latter provides sufficient power for headphones with low sensitivity. WIN SETTINGS With its two gain settings, the A90D Topping suits a wide variety of headphones. Combined with a noise floor of just 0.2 µVrms, even the most sensitive IEMs will not suffer from noise. INTEGRATED PREAMPLIFIER In addition to its headphone amplifier section, the A90 Discrete features a preamplifier circuit with unbalanced 20Ω outputs and balanced 40Ω outputs, compatible with most amplifiers on the market. Furthermore, both modes can be used simultaneously, and the remote control allows easy access to every function. CUSTOM VOLUME CONTROLS Finally, the A90 Discrete can be controlled via the R2R volume control with unique relays and resistors. This allows for extremely precise control with perfect channel balance and outstanding durability.
