Introduction to Accuphase

Accuphase Laboratory, Inc. is a Japanese, high-end audio equipment manufacturer founded by Mr. Jiro Kasuga in late 1972. The name ACCUPHASE was adapted by taking the prefix ACCU from the word “accurate” and combining it with PHASE, which is a critical factor in audio technology. Accuphase components are known to be the most high-end and high-powered presses. Accuphase has expertise in crafting Class A and Class AB amplifiers. Their endless pursuit of quality requires a very high degree of processing, which persuades Accuphase 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 all products are made in Japan.

Accuphase Amplifiers

Accuphase E-800 Class -A 50 watts into 8 Ω Stereo Integrated Amplifier

The E-800 is positioned above the E-650 as the new flagship model in Accuphase’s integrated amplifier line-up. The preamplifier section features the impeccable Balanced AAVA-type volume control. In contrast, the power amplifier section is configured as an instrumentation amplifier using a six-fold parallel push-pull configuration of power MOS-FETs driven in pure Class A. The resulting quality is on par with high-class separate-type amplifiers. Operating as a simple and intelligent system, the Accuphase E-800 realizes acoustic excellence that reaches the very heart of the music.

Accuphase E-800 features

  • Integrated amplifier with fully balanced configuration extending from input to output
  • Balanced AAVA-type volume control
  • Power amplification stage configured as an instrumentation amplifier
  • Six-fold parallel push-pull configuration of power MOS-FETs driven in Class A
  • Linear power progression of 50 watts into 8 ohms, 100 watts into 4 ohms, and 200 watts into 2 ohms
  • 300 W output into a 1-ohm load (music signals)
  • High damping factor of 1000
  • Strong power supply with massive high-efficiency toroidal transformer and large filtering capacitors
  • Protection circuit using MOS-FET switches

Accuphase Power Supply/purifier

The power supply delivers the energy your audio equipment uses for music playback. Accuphase’s Clean Power Supply components provide a power source with minimum noise and distortion by utilizing a groundbreaking waveform shaping technology that compares the power supply’s waveform to a reference waveform, supplements insufficiencies, and removes any excess misshaping. The results of waveform shaping are then observable in a new waveform display.
