Denon PMA-280 (1992–1995)
A compact stereo integrated amplifier from Denon’s early '90s lineup, delivering 45 watts per channel into 8 ohms.
Overview
The Denon PMA-280 is a solid-state stereo integrated amplifier produced between 1992 and 1995. It delivers 45 watts per channel into 8 ohms, making it suitable for driving a range of bookshelf and small floor-standing speakers of its era. Measuring 434 × 120 × 279 mm and weighing 6.1 kg, the unit combines a space-efficient footprint with Denon’s characteristic build discipline. While full specifications are sparse, the amplifier has appeared in the used market as a functional vintage component, often noted for its clean power delivery and compatibility with typical hi-fi systems of the 1990s.
Design
The PMA-280 has been subject to restoration work, with at least one known unit recapped to address aging components. A troubleshooting report on AudioKarma highlights that failures involving no output sound may stem from issues in the output stage, including output transistors and nearby resistors, capacitors, and transistors—suggesting a conventional solid-state output topology typical of Denon’s design approach during this period.
Market
In February 2024, a user on Reddit (r/BudgetAudiophile) reported acquiring a second-hand Denon PMA-280 for €70 as part of a budget-friendly vintage setup. Listings on Reverb and HifiShark indicate continued interest in the model among budget-conscious audiophiles and restorers, though specific pricing data beyond this anecdote remains limited. Common issues include complete loss of sound, requiring diagnosis of the output section.
