The Cambridge 840W is a high-end power amplifier that has been designed by the same team behind the 840A and uses an evolution of Cambridge Audio’s hugely innovative Class XD™ technology for a highly detailed naturally musical performance. The second generation Class XD is now complemented by a new output stage carefully adjusted to integrate with this novel technology, along with revised
balanced input connections for lower distortion and noise circuits.

This unique design gives pure Class A operation
at low levels, moving smoothly into an enhanced version of Class B at higher levels. The 840W delivers an impressive 200 watts per channel in
stereo mode, and can be bridged to output a massive 500 watt mono output.
