Selling my SMSL PA400, one of the newest GaN (Gallium Nitride) power amps on the market. Only used it for 2 days to test alongside my existing Class AB setup. Perfect for anyone interested in trying the new technology before spending a lot on new expensive GaN amplifiers. Also, great size for a d...
A compact, modern class-D power amplifier is the notable appeal here, but AUD 790 is a very ambitious ask against the used market. Across 248 comparable listings, the median is AUD 194, with the 75th percentile at AUD 362; this sits well above even the upper quartile, so it does not resemble a sensible used bargain unless the listing includes unusually valuable extras or exceptional provenance.
Its appeal is straightforward: the PA400 should offer clean, efficient power in a small chassis, making it a practical choice for a desktop, secondary system, or space-conscious stereo setup. At this price, though, the buyer should demand comprehensive specifications, clear photos, proof of fault-free operation, and the original packaging and accessories. Without those, a substantially lower figure would be more appropriate; the current ask is difficult to justify from the available listing detail.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
