Marantz SR-8100DC

The Marantz SR-8100DC is a big stereo receiver, rated at 2×100 watts into 8 ohms. Both sources that document the model agree on the core figures: frequency response of 20-20,000 Hz, total harmonic distortion of 0.02%, and dimensions of 440 × 151 × 366 mm at 12.8 kg. The "DC" is part of the model name in both sources.

Past the headline specs, the record gets thin. Signal-to-noise ratio is given as >90dB, with a phono figure of -75dB. Input sensitivity is listed at 2mV for phono and 160mV for line-level sources. Both of those come from single sources.

No production years, no original price, and no information on inputs, outputs, or tone controls have surfaced in the available documentation. What survives is a snapshot of a capable, high-powered receiver — one that clearly delivered serious wattage and clean distortion figures, but whose fuller story remains undocumented.
