Denon PMA-300V

Little is documented about the Denon PMA-300V, a compact integrated amplifier that appears to date from the late 1970s or early 1980s. What the record shows: it was a modestly powered unit, rated at either 30W or 2x 35W per channel into 8 ohms, depending on the source, with a frequency response extending from 5Hz to 100kHz. Total harmonic distortion was specified at 0.05%, and the signal-to-noise ratio at a respectable 105dB. It offered inputs for phono (MM), CD, tuner, aux, and two tape loops.

The PMA-300V was a lightweight, compact design for its era, measuring 434 x 85 x 282mm and weighing just 5.6kg — suggesting a slimline chassis aimed at the budget-to-midrange market. The damping factor of 60 is a modest figure, consistent with a smaller integrated amp of the period.

Beyond that, surviving information is thin — no production years, original pricing, or design details have been confirmed.
