McIntosh MA6300 483,000yen(around the including-tax and 2007 time)

Integrated amplifier which condensed the know-how of making the sound of mac tradition.

The electromagnetic switch which enclosed inert gas is adopted. It is strong to oxidization, and the distorted signal switchover which is not is enabled, without raising a poor contact over a long period of time.

R core type power transformer of mac original is adopted as a power-source part. The voltage stabilized also in the voltage fluctuation of AC can be supplied, and it has a structure strong also against a noise.

When a difference arises in an input/output wave exceeding the maximum power capacity, the dynamic operating time, voltage, and electric current of the power guarding in which a comparator restricts gain and controls distortion of an output, and an output stage are supervised, and the sentry monitor circuitry controlled to suppress an electric current in safe level is carried.
Furthermore, protection networks, such as DC protection, a temperature protection, a turn-on latency, and an in rushes protection, are adopted.

The blue-eyes power meter which displays the output power actually outputted is carried.
