About this model

The Quad 405-2 is a stereo power amplifier built around Peter Walker's Current Dumping design, which pairs a low-power Class A driver with a robust Class B output stage. It delivers 100 watts per channel into 8Ω and 100 watts into 3Ω, and is rated for 4Ω to 16Ω nominal speaker loads. A load-sensitive dynamic protection circuit, less aggressive than the original 405's, lets it cope better with demanding low-impedance speakers. Frequency response runs from 20Hz to 20kHz, with a signal-to-noise ratio of 95dB to 96dB. It has no power switch and is typically switched on from a connected Quad preamplifier such as the 33 or 44 via a special interconnect cable.

A great opportunity to own a Quad 405-2 at this price point.
