Tonewinner AD-5100PA+ Power Amplifier Fantastic condition. Well looked after. A really nice amp for the money. (2 available). Located in Berwick. Power Output / Channel: - 117watts RMS/channel; 20 Hz – 20 kHz; THD
Is A$820 a smart buy for a used Tonewinner AD-5100PA+, or are you overpaying for heritage? At A$820, this listing sits well below the typical new retail price of A$1,099 and is significantly cheaper than recent international new listings hovering around A$900–A$950, making it a strong deal for a well-regarded 5-channel Class AB amplifier.
The AD-5100PA+ earns respect for its audiophile-grade toroidal transformer, delivering 5×100W with low distortion (<0.009% THD) and robust cooling, ideal for driving ceiling speakers or multichannel setups. Its automatic voltage detection (115/230V) adds versatility, and the 9.6kg build suggests durability. Since the condition is listed as unknown but the price is below median new cost, this is a buying opportunity for enthusiasts seeking serious power without Marantz-level prices—just verify operation before committing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
