It also functions as a preamp, making it suitable for connecting to power amplifiers for driving speakers.

When paired with the TOPPING D90SE/LE DAC, the A90 Discrete forms an almost distortion-free HPA + DAC combination. It can also be paired with the TOPPING LA90 Class AB Power Amplifier, providing precise volume control, remote control, and additional input options.

The A90 Discrete utilizes fully discrete components to redesign the NFCA module, providing excellent DC and AC performance with low distortion and noise.

The inclusion of a ground loop noise terminator and the ability to switch between headphone amp and preamp modes further enhance its versatility. The A90 Discrete also incorporates R2R relay volume control, allowing for precise control, longevity, channel balance, and remote control operation.
