Accuphase P-300


It is a mistake to calculate the value of a power amplifier solely in terms of $/power or cost/power.

Other more important factors should also be considered to assess its overall value such as those power qualities like low distortion, well-regulated power supply and power bandwidth, as well as additional functions and appearance values.

Music delivered through a good power amplifier should have an extra quality of deep, rich bass and the subtle nuances of inner musical fabric which stir and warm the soul with emotion.

A good power amplifier must also have the range to reproduce precisely the softest to the loudest passages of music, and, at the same time, it must be able to handle, without distorting, all the large input amplitudes that may be involved.

The P-300 can coast through all of these requirements without strain due to its large, heavy-duty power transformer and 2 x 40,000 microfarad filter capacitors, its all-stage, push-pull circuit configuration, and well selected and thoroughly tested parts.
