Key specs that matter
Input sensitivity is specified at two reference points - 220mVrms for 1W into 8 ohms, or 2.2Vrms for the full 100W into 8 ohms - a detailed dual-reference specification uncommon among commercial power amplifiers. Input impedance is a substantial 47,000 ohms on both connections. Output power is 100W into 8 ohms. Gain is 22dBu. At 260 x 585 x 275mm and 35kg, the AFM100 Special Edition's considerable weight for its power output reflects serious internal engineering.
Sound and use context
Expect a dependable, precisely characterised amplification performance reflecting the detailed dual-reference sensitivity specification, consistent with Riviera's broader considered engineering philosophy.
Pairing
As a monoblock, two units are needed for a stereo pair, and Riviera's own APL1 preamplifier offers a natural, brand-coherent pairing.
Alternatives
Other manufacturers' comparable monoblock power amplifiers offer alternatives for buyers wanting to compare features at a similar price point.
