Wharfedale MP1800 Power Amplifier 2x400W @ 4Ohm / 2x260W @ 8Ohm. The steel casing and sturdy construction are only the beginning. Internally MP amps uses extremely reliable components and comparatively simple amplification circuitry. This means that should something happen, MP amp is simple to repair.
Over 1/3rd of the internal chassis is taken up with a massive toroidal transformer. This gives an MP amp the power supply stability to function in the most extreme AC conditions. MP amps are also stable down to 2 Ohms. This allows for multiple 8 Ω or 16 Ω speakers to be driven with extreme and constant power.
