This is a great sleeper amplifier. The brand is well known in Europe and manufactured by a subsidiary of the Mclaren Group that produces championship winning Formula One race cars. Quite a pedigree.
These amps actually measure a lot higher than the published 100W spec. In reality they're able to achieve 156/244/270 Watt continuous power at 8/4/2 Ohm, which is more than enough to drive any speaker.
