Accuphase E-270 Integrated Amplifier

Taking the integrated amplifier to further heights

Pursuit of performance and sound quality results in capability well beyond its class, approaching the level of separate type amplifiers.
Revolutionary AAVA volume control. A power amplifier section featuring high power transistors in parallel push-pull configuration, complemented by a robust power supply and low impedance output stage. 120 watts of quality power into 4 ohms, with a damping factor of 400. Current feedback amplifier topology assures excellent phase characteristics in the high range, and instrumentation amplifier principle enables fully balanced signal paths. Power MOS-FET switches in the protection circuitry eliminate the need for mechanical contacts.

AAVA volume control with further lowered noise floor

The volume control in the preamplifier section is a crucial component with a decisive influence on performance and sound quality. AAVA is a revolutionary type of completely analogue volume control that completely does away with any variable resistors in the signal path. This ensures that the signal remains perfectly unaltered, free from the adverse effects of impedance changes. As a result, both S/N ratio and sound quality are excellent at any volume setting.

Features

• Configuration with a total of 18 V-I converter amplifiers, paralleled for upper two units, reduces overall AAVA impedance to one half and results in lower noise. Input stage with five buffer amplifiers ensures powerful drive capability
• No more left/right tracking differences or crosstalk
• Attenuator and balance control also implemented by AAVA, eliminating additional circuitry
• Operation feel is exactly the same as a conventional volume control, and remote control is also possible
• Combination of 16 types of weighted V-I converter amplifiers gives 65,536 possible volume steps
• Volume level can be displayed accurately as a numeric indication

Designed for Maximum Sound Quality

Parallel push-pull output stage and power amplifier stage mounted on large heat sink. Two identical units are arranged on the left and right sides of the chassis.
Power amp units use high-power transistors in a robust parallel push-pull configuration, producing ample output of 120 watts into 4 ohms or 90 watts into 8 ohms per channel.
Strong power supply with massive high-efficiency transformer and large filtering capacitors. The E-270 uses a massive power transformer with high output capability. Highly effective filtering is realized with two custom-made aluminium electrolytic capacitors, each with a vastly increased 30,000 μF rating.

Advanced Features

• Protection circuitry employs semiconductor (MOS-FET) switches for low impedance and excellent long-term reliability
• Two sets of large speaker terminals. Y lugs and banana plugs are also supported
• Balanced remote sensing technology provides balanced feedback for both the signal and GND lines from near the speaker terminals to ensure low impedance and high damping factor. Minimizing the amplifier's output impedance results in a damping factor of 400
• Bi-wiring connection using the two sets of speaker terminals is supported
• Analogue peak power meters with new LED lighting for improved legibility
• Versatile array of input options including balanced inputs to shut out external noise interference
• MAIN IN button and preamplifier output and power amplifier input connectors allow independent use of both sections
• Individual phase setting is possible for each input position (with memory)
• Logic-controlled relays for signal switching assure high sound quality and long-term reliability
• Dedicated headphone amplifier optimized for sound quality
• "High Carbon" cast iron insulator feet with superior damping characteristics further enhance sound quality

Shipping Rates

We calculate your shipping rate based on the total weight of your items and your delivery address. Standard shipping to the UK Mainland (excludes Northern Ireland, Isle of Man, Channel Islands) is free, except where specifically indicated. Don't worry, you'll always see the final shipping charge displayed before you reach the payment step (on the checkout page).

Carriers

We despatch the bulk of our UK mainland items on a 24 hour service.  Non-Mainland locations – Isle of Man, Isle of Wight, the Scilly Isles, the Scottish highlands and Islands, the Channel Islands and Northern Ireland may take a day or so longer. Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as UPS and occasionally by a Pallet service.

Order Tracking

If a tracking # is provided by the carrier, we will update your order with the tracking information. Please note that some orders will not have tracking numbers.
