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.
Output stage with 10-parallel push-pull arrangement in
each channel delivers ample power down to extremely low load impedances
of 1 ohm
Amplification stage features low-noise instrumentation amplifier topology
Further refined MCS+ circuit
Current feedback principle combines excellent sound quality with total operation stability
Bridged connection mode allows upgrading to monophonic amplifier
4-stage gain control
Newly developed massive toroidal transformer with high power capacity
Specificatii Amplificator de Putere Accuphase P-7300
Music is an oasis that refreshes us in our journey of life.
Music can be soothing, exciting, exhilarating. It can move our hearts and enrich our lives, which is the goal we at Accuphase seek through audio technology.
This was the idea behind the slogan "Enrich Life through Technology" which originally brought together the group of very highly skilled audio experts who conceived and today produce the successful Accuphase line of audio equipment. It is the guiding principle behind all Accuphase components whose high grade can be considered extravagant. Just as there are exquisite musical instruments that are especially highly prized, we believe that the same applies to audio components. This belief forms the basis of our design concept. It is the reason why we strive to build extra value into each of our units so that they will display fully the merits of hand construction.
The name ACCUPHASE was adapted by taking the prefix ACCU from the word "accurate", and combining it with PHASE which is a most important factor in audio technology. We feel it is a very fitting brand name to describe our products that fully portray this and other important characteristics, which penetrate the innermost depth of audio technology. Our endless pursuit of quality requires a very high degree of processing which persuades us to avoid the use of mass production systems. Consequently, production volume is limited and Accuphase products are available only at a restricted number of specialized stores.
Accuphase equipment is not subject to the whims of market fashion since they are made, above all, to achieve true high fidelity sound reproduction. This is the foremost reason why our products have enjoyed long-run production.
