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. Many people have mistaken the A308CR's extraordinary cleanness for lack of power. This is because the massive power makes it nearly impossible to clip or over-drive the A308CR power amp and, as it's always running easily, it will never produce any harsh sounds or unpredictable distortion patterns.
Features :
- New circuit (Very low distortion over a very wide bandwidth, very wide stability margins and low feedback. Great sound.)
- Full choke regulation. (Incredibly clean power supply lines because any mains interference is eliminated and, as a result, circuitry can operate at its optimum.)
- Dual Mono. (Better transient response and imaging. Also greater depth of field.)
- High power. (Realistic and wide dynamic range.)
- Low distortion and wide bandwidth. (Clean, clean sound.)
- Loop out. (Allows very easy passive bi-amping.)
- Two switchable inputs. (When the A308CR power amp is connected to two systems at the same time, it is easy to switch between them.)
