NAD Model 208

Documentation on this model is thin. The archive's research has turned up no production years, no original price and no detailed circuit analysis.

The most consistent figure across sources is 225W per channel into 8 ohms. Three separate references agree on it. A fourth source lists 230W, which looks like an outlier. The 4-ohm figure is conflicted: one source says 280W, another says 360W. The archive won't pick one without better authority. Frequency response is documented at 20Hz-20kHz ±0.1dB by two independent sources. The design is described as Class A/B with a direct-coupled output stage and all-discrete, quasi-complementary output devices. A 1993 review in HiFI-Stereo notes that NAD models with Power Envelope circuitry have extended headroom, and that NAD's Soft Clipping circuitry is designed to prevent speaker-damaging distortion (HiFI-Stereo, 1993, p.106). Signal-to-noise ratio is stated as greater than 115dB, and damping factor above 500. Both are single-source claims. Input sensitivity is 1.5V.

Physical specs come from one source: 437 x 180 x 400 mm (W×H×D) and 25 kg.

A lot is missing. There is no confirmed release year, no original list price, no input/output connector details beyond sensitivity, no power consumption figure, and no subjective listening impressions from period reviews. If you own one and have the manual or service literature, the archive would welcome the details.
