Denon POA-2200 High-End Dual-Mono Power Amplifier — Restored

Classic high-current Japanese power amplifier from Denon’s golden era. The Denon POA-2200 is a true dual-mono design built to drive demanding speakers with authority, combining massive power reserves with refinement and control.

This unit has been carefully restored by an enthusiast and is performing excellently.

Restoration & Upgrades
Full recap — all electrolytic capacitors replaced throughout
Main filter capacitors upgraded:
8 × 10,000 µF / 100 V high-quality capacitors
Power rectifiers upgraded for improved reliability
New high-quality speaker binding posts installed
Internals cleaned, inspected, and tested
Runs stable, quiet, and cool

This was a thorough restoration carried out with care — not a superficial service.
Performance
True dual-mono architecture (separate amplifier boards per channel)
High current capability — drives difficult speakers effortlessly
Excellent bass control and dynamics
Clean, detailed, neutral presentation
Suitable for both modern and vintage high-end systems

Condition
Fully functional following restoration
Very good cosmetic condition for its age (see photos)
Heavy, overbuilt construction typical of late-80s flagship gear

Note: There is a very slight channel level imbalance. This is minor in practice and easily corrected with a tiny adjustment of the preamp balance or Poweramp output level control to achieve a perfect centre image. No distortion, noise, or other faults to my ears.

Specifications (approx.)
200 W per channel into 8 Ω
Higher output into 4 Ω
Massive transformer and power supply
Weight: approx. 25 kg
