The P-7300 inherits technology features and concepts of the 40th
anniversary commemorative model A-200 and subsequent M-6200 and takes
these even further. Some of the highlights are a drastic reduction in
noise and a significant further improvement of the damping factor.
In the final stage, the parallel configuration of output devices
ensures high current capacity and keeps the output impedance of the
power amplifier extremely low. In addition, intensive research has
culminated in an improved NFB loop with remote sensing, and the use of
MOS-FET switches characterized by low ‘on-resistance’.
This further improves the ability to handle any speaker with
competence, realizing constant-voltage drive even with extremely low
load impedances. The guaranteed damping factor of at least 1,000
demonstrates the impressive success of this approach. In addition, by
further refining the parallel drive and gain allocation of the input
stage, Accuphase engineers were able to push the noise floor to
previously unthinkable levels, achieving an amazing signal-to-noise
ratio of 125 dB at maximum gain and 131 dB at the –12 dB gain setting.The P-7300 delivers 125w into 8 ohms
