Description :
The A308CR dual mono power amplifier is a killer. It's rated at 250 watts per channel, and can deliver blockbusting current, high voltage and, at the same time, it has incredibly low distortion over a very wide bandwidth and loading range. Inside the A308CR dual mono power amp is Musical Fidelity's latest circuitry, with a completely separate power supply for the output stage. The printed circuit board layout used new techniques that we have developed alongside the circuitry. As a result, the performance is almost unbelievable. For example, distortion at 40kHz is less than 0.01% (that's not a typo).
This amplifier has colossal headroom, slam and attack, and yet it is incredibly detailed and sweet. A particular quality of the A308CR power amp is its extraordinary delicacy which, at first acquaintance, has the subtlety and pinpoint accuracy normally associated with small amplifiers. But the transient attack is something else again.
