Accuphase Precision Integrated Amplifier E-800

Accuphase E-800

All New 50th Anniversary Precision Integrated Amplifier

Accuphase simply do not do this often, that is, introduce a totally new product. The all new E-800 takes it’s place alongside the C-3850, A-250 and DC/DP-950 as the Precision flagship model in the already impressive line line up. As desirable as this new machine may be, we should perhaps take a moment to reflect on the Anniversary aspect.

Fifty years is a long long time in audio history. Sure we still have many of the famous marques, Krell, Levinson, Audio Research, Luxman, Marantz and so on, the list is extensive. But few if any can trace their ownership, location and importantly, manufacturing culture and philosophy, as a single unbroken steadfast thread to the very first day the Institution “Accuphase” was born.

For those readers who may wonder about the Accuphase mystique and whether it is justified. I would suggest a visit to the Accuphase website and peruse the company philosophy manifesto. In a nutshell, the brand is simply uninterested and therefore untroubled with growth, outside shareholders, changing fashions and new technologies (streaming) until the technology in question is mature and 100% reliable.

Accuphase really only have two masters. Firstly they are a slave to the appreciation of the musical art form. After all that is the function of the equipment, to deliver music in the finest manner possible. The second master is that of craftsmanship and again, the finest quality possible, that music enthusiasts, like you and I, might aspire to.

The all new E-800 Class A Precision Integrated Stereo Amplifier sets a benchmark that most others can only dream about.

Accuphase E-800

Integrated Amplifier Is First Entry in New Flagship Model Series

The E-800 is positioned above the E-650 as the new flagship model in the integrated amplifier line up of Accuphase. The preamplifier section features the impeccable Balanced AAVA type volume control. And 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 a par with high class separate type amplifiers. Operating as a simple and smart system, the E-800 realises acoustic excellence that reaches to the very heart of the music.

Ultra-Massive Pure Class-A Precision Integrated Amplifier Combining cutting-edge technology with carefully selected materials of superb quality, the E-800 exudes an aura of solid luxury, with a lavish champagne gold front panel that changes its look depending on the viewing angle, and bar graph meters that delicately reflect the rhythm of the music.

Formidable power amplification stage. The power amplification circuitry mounted directly on a large heat sink employs a six-fold parallel push-pull configuration of power MOS-FETs driven in Class A. Two identical units arranged on the left and right sides of the chassis deliver impeccable power in a linear progression for the two channels. 50 watts into 8 ohms, 100 watts into 4 ohms, and 200 watts into 2 ohms. The amplifier can even supply 300 watts into 1 ohm (music signals).

Power supply circuitry designed for optimum stability. The strong power supply with massive high efficiency toroidal transformer and two large 60,000 μF filtering capacitors ensures a stable current supply at all times.

Balanced AAVA type volume control. AAVA performs volume adjustment by making use of a combination of 16 current signals with different magnitude. This thereby eliminating signal degradation and impedance fluctuations and maintaining high S/N ratio and low THD over the entire volume range. In the Balanced AAVA implementation of the E-800, two AAVA circuits are driven in a fully balanced configuration with a superior capability to eliminate external noise.

High-accuracy, high-rigidity volume sensor construction. The volume sensor mechanism developed by Accuphase in-house is built from a single massive aluminium block extruded and finished with utmost precision and complemented by other substantial materials, to ensure a silky smooth operation feel.

High damping factor brings out the full musical potential of loudspeakers. Features such as Balanced Remote Sensing and MOS-FET switches help to realise a damping factor of 1000. Superb motion control lets every loudspeaker perform at its very best.
