It draws directly on engineering developed for the E-800, the model built to mark Accuphase's 50th anniversary, and applies that engineering at a more attainable point in the catalog. The result is 35 watts per channel into 8 ohms in pure Class A operation, rising to 70 watts into 4 ohms, 140 watts into 2 ohms, and a peak of 160 watts into 1 ohm. Those numbers sound modest next to high wattage Class AB amplifiers, and that is by design. Class A operation trades raw output for linearity, keeping every output device biased on and active regardless of signal level, which is what gives Class A amplification its characteristic smoothness and freedom from crossover distortion.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" style=\"text-align: center;\"\u003e\u003cstrong\u003eBalanced AAVA and the ANCC Noise Canceling Circuit\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" style=\"text-align: center;\"\u003eAt the heart of the E-700's preamplifier section is Accuphase's Balanced AAVA volume control, short for Analog Vari gain Amplifier. Rather than using a conventional variable resistor to set volume, which changes impedance as it's adjusted and can subtly color the signal, AAVA controls gain electronically across more than 65,000 discrete steps, so the signal path itself never changes character regardless of listening level. Working alongside AAVA is ANCC, the Accuphase Noise and Distortion Canceling Circuit. ANCC detects noise and distortion introduced at the earliest stage of the volume control's current to voltage conversion and injects a canceling signal of reversed polarity to eliminate it before it reaches the rest of the circuit. Accuphase states the combination reduces output noise voltage by 11 percent compared to the outgoing E-650, with a guaranteed signal to noise ratio of 103 decibels.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" style=\"text-align: center;\"\u003e\u003cstrong\u003eFourfold Push Pull Power Amplification\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" style=\"text-align: center;\"\u003eThe power amplifier stage is where the E-700 makes its clearest step up from its predecessor. Accuphase moved from a three element parallel push pull MOSFET output stage in the E-650 to a four element configuration in the E-700, the same basic architecture used in the Class A power amplifier A-80. Adding a fourth output device per channel increases both current delivery and long term reliability, and it's a meaningful part of why Class A output climbed from 30 watts in the E-650 to 35 watts here. The output stage is fed by a large toroidal transformer and a newly developed 56,000 microfarad filter capacitor bank, giving the amplifier a deep reserve of current for demanding musical peaks even though it never leaves Class A operation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" style=\"text-align: center;\"\u003e\u003cstrong\u003eFully Balanced From Input to Output and a Damping Factor of 1,000\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" style=\"text-align: center;\"\u003eSignal integrity matters as much as raw power in a component at this level, and the E-700 keeps its signal path fully balanced from the moment it enters the amplifier to the moment it reaches the speaker terminals. That balanced architecture, combined with the low output impedance of the four element output stage, gives the E-700 a guaranteed damping factor of 1,000 into an 8 ohm load, a 25 percent improvement over the E-650 and a figure that matches Accuphase's own A-80 power amplifier. Damping factor describes how tightly an amplifier controls speaker cone movement after a signal stops, and a figure this high means the E-700 can grip low frequency drivers with authority, which matters especially with harder to drive speakers.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" style=\"text-align: center;\"\u003e\u003cstrong\u003eExpansion Slots and What They Add\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" style=\"text-align: center;\"\u003eThe E-700 ships without a built in DAC or phono stage, and that's intentional. Two expansion slots on the rear panel accept Accuphase's optional DAC-60 digital input board or AD-60 phono equalizer board, and both can be installed at the same time. The DAC-60 adds USB, coaxial, and optical digital inputs with support up to 384kHz PCM and DSD256. The AD-60 adds a moving coil and moving magnet capable phono stage with four selectable MC input impedance settings and fixed gain of 66dB for MC and 40dB for MM cartridges.

The E-800S delivers roughly 50 watts per channel in Class A and sits at a meaningfully higher price point, with a more elaborate feature set to match. The E-700 gives up some of that headroom and polish but keeps the core of what makes Accuphase's Class A amplifiers distinct: the Balanced AAVA volume control, ANCC noise cancellation, and a fully balanced signal path, at a price that puts pure Class A ownership within reach of more listeners. For anyone who wants the Accuphase Class A sound without stepping up to flagship pricing, the E-700 is the amplifier built specifically for that decision.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\" style=\"text-align: center;\"\u003eKey Specifications\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eAmplifier Type: Fully balanced Class A integrated stereo amplifier\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eOutput Power: 35W per channel into 8 ohms, 70W into 4 ohms, 140W into 2 ohms, 160W peak into 1 ohm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eOutput Stage: Fourfold parallel push pull MOSFET, pure Class A\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eDamping Factor: 1,000 guaranteed (8 ohm load)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eVolume Control: Balanced AAVA with ANCC noise and distortion canceling circuit\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eFrequency Response: 3Hz to 150kHz (+0\/-3dB)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eTotal Harmonic Distortion: 0.03% (8 to 16 ohms), 0.05% (2 to 4 ohms)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eSignal to Noise Ratio: 103dB guaranteed\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eInputs: 5 RCA line inputs, 2 balanced XLR inputs, unbalanced and balanced preamp in\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eOutputs: Balanced and unbalanced preamp out, monitor\/recorder loop, headphone jack\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eExpansion Slots: 2, compatible with DAC-60 digital input board and AD-60 phono equalizer board (sold separately)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eSpeaker Terminals: Dual sets (A, B, or A+B)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eRemote Control: Included\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eFinish: Champagne gold front panel with illuminated VU meters\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eDimensions (W x H x D): 465mm x 191mm x 428mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" style=\"text-align: center;\"\u003eWeight: 24.9kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: center;\"\u003e \u003c\/p\u003e","brand":"Accuphase","offers":[{"title":"Default Title","offer_id":45931423858918,"sku":"","price":15975.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/0645\/2454\/files\/e-700.jpg?v=1784663863","url":"https:\/\/theaudiosolutions.com\/products\/https-theaudiosolutions-com-products-accuphase-e-700-class-a-precision-integrated-stereo-amplifier","provider":"Audio Solutions","version":"1.0","type":"link"}
