Inheriting many outstanding technology features of the A-200, the A-70 represents a full model change from the A-65, ready to take its place as the ultimate pure class A stereo power amplifier. While reflecting this tradition, the A-70 also implements latest technology such as the ultra low-noise instrumentation amplifier principle realized in a discrete configuration, along with optimized signal input and power amplification stages, resulting in an astonishing 127 dB S/N ratio (at -12 dB gain), surpassing even the formidable earlier Accuphase stereo amplifier lineup.
The output stage of the A-70 features power MOS-FETs renowned for their excellent frequency response, sonic performance, and superior reliability. In the output circuitry, ultra-heavy-gauge edgewise coils with a surface area more than three times larger than conventional units, combined with MOS-FET switches are used in place of relays, to eliminate mechanical contacts and improve long-term reliability. Top-grade materials, sophisticated circuit pattern technology, and various other measures result in low impedance and enable the realization of a damping factor of 800, which represents a two-fold improvement over the A-65.

  • Pure Class A operation delivers quality power: 60 watts x 2 into 8 ohms
  • Power MOS-FET output stage features 10-parallel push-pull configuration and delivers linear high power progression to ultra-low 1-ohm impedances
  • Ultra low-noise instrumentation amplifier principle used in input stage
  • Amplification stage implements further evolved MCS+ topology
  • Current feedback principle combines stable operation with outstanding sound quality
  • Bridged connection mode allows upgrading to monophonic amplifier
  • Two selectable meter types: digital power meters showing true power values and bar graph indicators

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.
