Our Thoughts RADAR AI

This A$650 asking price for the Topping A90 Discrete is a genuine bargain, sitting well below the 25th percentile of A$681 and offering significant value compared to the median of A$713 in the used market. While the retail price is around A$900, finding a used unit this far under the typical range signals an excellent buying opportunity rather than a lukewarm deal.

The A90 Discrete is highly regarded for its fully discrete gain stage using 156 matched transistors, delivering exceptional neutrality, ultra-low distortion under 0.00005%, and massive power output of 580mW into 32 ohms. It also doubles as a fully balanced preamplifier with XLR and RCA outputs, making it a versatile flagship performer. At this price, the A$650 listing represents a smart investment for a well-loved, high-spec amplifier that typically commands much higher used values.
