Denon PMA-700V
The Denon PMA-700V is a vintage integrated amplifier that appears to have been built around a serious phono stage and a dual-mono layout. The record on this model is thin - most of what survives comes from a single dealer listing - but the documented specs point to a well-engineered mid-to-high-end component.
The amplifier is rated at 80 watts per channel into 8 ohms (DIN, 20Hz - 20kHz, ≤0.05% THD). Total harmonic distortion is claimed at just 0.01% at rated output. Frequency response is specified at 10Hz - 50kHz (+0/-3dB). Damping factor is 150 at 8 ohms, 1kHz. The design highlights are dual mono construction, a high-current power supply, discrete component circuitry, pure copper internal wiring, and gold-plated RCA terminals.
The phono section is where the PMA-700V stands out. It has both MM and MC inputs with a "high quality" stage. MM sensitivity is 2.5mV with an overload margin of 140mV, and MC sensitivity is 0.15mV. Signal-to-noise figures are listed at 80dB for MM and 101dB for line-level sources. The surviving documentation disagrees with itself on the MC signal-to-noise ratio. It gives 79dB in the main spec list and 74dB in the MC description. The former is listed here as the headline figure, but both appear in the record.
Inputs are limited to four: Phono, CD, Tuner, and AUX. The documentation says nothing about tape loops, tone controls, a headphone output, or speaker switching. The unit may well have them, but they're not part of the surviving record.
HiFI-Stereo (February 1987, p.103) covered Denon amplifiers of this generation in its equipment listings, noting the company's attention to phono flexibility and input switching — context that fits the PMA-700V's apparent priorities, though no specific review of this exact model has surfaced.
Beyond that, almost nothing else is documented. No original price, no weight or dimensions, no production numbers, and no market values today. What's known is what's listed above — and for a Denon integrated with a proper dual-mono layout and a serious MM/MC phono stage, that's a respectable amount to go on.
