Description
Brand: TOPPING
Characteristics:
- Fully Discrete NFCA Headphone Amplifier: The A9 Discrete utilizes fully discrete components to redesign the NFCA module. Four integrated discrete NFCA modules, each with 39 transistors, form a fully symmetrical structure. The output power is stronger than ever, allowing the amplifier to drive low-impedance headphones more effectively.
- The discrete A9 TOPPING also serves as a preamplifier: In preamplifier mode, it achieves the same high performance as in headphone amplifier mode, and the balanced output impedances of 2 ohms SE and 4 ohms are widely suitable for various amplifiers. The A9Discrete not only outputs from the headphone amplifier (headphone jack output only) to the preamplifier (RCA and XLR only), but also supports simultaneous output from all of them.
- Ground loop noise reduction: Ground loop noise can occur when multiple devices are used in combination. A9Discrete features a GND/LIFT switch to solve this problem. Set it to GND during normal use. If you detect ground loop noise, switch to LIFT to eliminate ground loop noise.
- Combination in a TOPPING set: The A9 Discrete can be used with the TOPPING D9SE/D9LE DAC, which is essentially a lower-distortion HPA+DAC combination. The A9 Discrete can also be used as a preamplifier for the TOPPING LA9, providing more precise volume control, remote and remote control, and an auxiliary input.
- Gain Settings: The discreet A9 features two gain settings that are sufficient for a wide range of headphones: low gain for high sensitivity and high gain for standard over-ear headphones. Combined with the very low noise level of 0.2 µVrms, this ensures no noise even with sensitive IEMs.

Details: TOPPING A90 Discrete HiFi Headphone Amplifier, Fully Discrete Balanced, 9800mW x 2 NFCA 4-pin XLR/4.4MM/6.35MM SE Output Preamp for Home Audio Headphones with Remote Control and 2 Preamp Amplifier Controls. Discrete A90 is the discrete component of TOPPING A90 headphone amplifier. Contains almost all the functions of TOPPING A90 and Pre90. In addition to using discrete components to form an amplifier circuit, the following features have been added: 1. Higher output power 2. Using relay for volume control, supporting many custom volume controls 3. Remote control bracket for easy operation 4. Discrete A90 provides 1 XLR input and 1 stereo RCA input, but when working with TOPPING Ext90, it can provide 4 XLR inputs and 2 stereo RCA inputs. 5. Add a ground loop interrupter to solve the ground loop problem. 6. Add a 12V trigger function, which can be synchronized with other devices with the same interface. Dimensions: 16 x 22.2 x 4.5 cm. Accessories: 1 x A90 discreet taping, 1 x remote control, 1 x AC power cable, 1 x 6.35 mm to 3.5 mm adapter, 1 x user manual.
