Accuphase E-650 Class-A Precision Integrated Stereo Amplifier
About
Ooberpad announces the availability of the power-packed Accuphase E-650 Class-A Precision Integrated Stereo Amplifier. Innovative engineering and top-grade parts and materials synergise in this product featuring the remarkable Balanced AAVA type volume control and a triple parallel arrangement of power MOS-FETs in the output stage. The power amplifier section employs the breakthrough instrumentation amplifier configuration for balanced signal transmission, leading to an integrated amplifier with a fully balanced configuration from the inputs right through to the output. The massive power supply and low-impedance output circuitry pack punch with 150 watts per channel (into 1 ohm, with music signal) and a damping factor of 800.
Warranty
1-year manufacturer's warrantyKey Features:
- First integrated amplifier featuring Balanced AAVA volume control
- Pure Class A operation(30 watts into 8 ohms)
- Guaranteed linear power: 120 watts into 2 ohms, 60 watts into 4 ohms,30 watts into 8 ohms
- The output stage with power MOS-FETs in triple parallel push-pull configuration
- Instrumentation amplifier principle in the power amplifier for fully balanced signal transmission, complemented by MCS+ topology and current feedback amplification circuitry
- Strong power supply with massive high-efficiency transformer and large filtering capacitors
- Preamplifier and power amplifier sections can be used separately
- Numeric indication of volume level
Benefits of Accuphase E-650 Class-A Precision Integrated Stereo Amplifier:
Balanced AAVA volume control
As a first in an integrated amplifier, the E-650 features the sophisticated Balanced AAVA type volume control incorporated in Accuphase's top-of-the-line preamplifier model C-3850. Balanced AAVA uses two AAVA circuits driven in a fully balanced configuration. This completely cancels out any external noise and results in an unsurpassed S/N ratio.
High-accuracy, high-rigidity volume sensor construction
AAVA uses a volume control knob that looks similar to conventional controls. However, Accuphase also paid careful attention to volume sensor construction. The rotary mechanism is assembled with high accuracy and mounted to a highly rigid frame extruded from a single aluminum block. The solid brass shaft has a diameter of 8 mm and gives a pleasingly massive yet responsive operation feel to the volume knob. Floating suspension technology developed by Accuphase for its SA-CD/CD players is used to mount the volume sensor mechanism to the main chassis. Furthermore, utterly smooth and quiet operation is assured also when adjusting the volume with the remote commander, thanks to insulators that dampen any vibrations of the drive motor.
High-efficiency toroidal transformer
The E-650 uses a massive power transformer with high output capability. Highly effective filtering is realized with two custom-made aluminum electrolytic capacitors, each with a large 50,000 µF rating.
Sound Quality
Triple parallel push-pull output stage with power MOS-FETs and power amplifier stage mounted on a large heat sink. Two identical units are arranged on the left and right sides of the chassis. Class A operation (30 watts into 8 ohms). Guaranteed linear power of 120 watts into 2 ohms, 60 watts into 4 ohms, 30 watts into 8 ohms per channel.
