The Accuphase E-3000 integrated amplifier stands as a testament to the cutting-edge technologies derived from high-end audio equipment. With a meticulous design that prioritizes sound quality and performance, the E-3000 brings forth a listening experience that audiophiles will deeply appreciate.

AAVA Volume Control Circuit

At the heart of the E-3000 lies the AAVA (Accuphase Analog Vari-gain Amplifier) volume control circuit. Utilizing the ANCC (Accuphase Noise Cancellation Circuit) principle, this innovative technology ensures that volume adjustments maintain sonic integrity, providing a clean and precise audio signal throughout its range. This design choice reinforces Accuphase’s commitment to delivering a superior listening experience.

Powerful Amplification

The E-3000 is not just about elegant circuitry; it boasts formidable power output as well. Delivering 100 watts into 8 ohms and 150 watts into 4 ohms, this amplifier is capable of driving a wide range of speakers with ease. The power amplification stage is configured as an instrumentation amplifier, producing balanced signals that enhance audio clarity and fidelity.

Advanced Power Amplification Technology

The amplifier employs a three-fold parallel push-pull configuration, utilizing power transistors driven in Class AB mode. This architecture not only contributes to a robust output stage but also ensures a high damping factor of 600. The high damping factor improves control over speaker motion, resulting in tighter bass response and greater overall sound accuracy.

Balanced Remote Sensing

To further refine its performance, the E-3000 integrates balanced remote sensing technology. This feature enhances the damping factor even more, ensuring that the amplifier maintains excellent control over the connected speakers, regardless of the impedance or load conditions.

Current Feedback Amplification

The current feedback amplification circuit topology employed in the E-3000 guarantees excellent phase characteristics in the high range, preventing distortion and maintaining signal integrity. This design choice is crucial for delivering the detailed and dynamic sound that audiophiles seek.

Robust Power Supply

The E-3000 is powered by a strong power supply, featuring a massive transformer and high-voltage, large filtering capacitors. This substantial power reserve ensures that the amplifier can handle demanding audio passages without strain, resulting in a clean and powerful sound reproduction.

Comprehensive Protection Circuitry

Safety and reliability are paramount in any high-end audio component. The E-3000 incorporates protection circuitry using MOS-FET switches, safeguarding the amplifier and connected speakers from potential damage due to overload or short circuits.

Versatile Tone Controls

To cater to personal audio preferences, the E-3000 includes tone controls that utilize summing active filters. This allows users to tailor the sound to their liking, enhancing the listening experience based on individual tastes and room acoustics.

Superior Vibration Damping

Construction quality is not overlooked, as the E-3000 features high-carbon cast iron insulators designed for superior vibration damping. This attention to detail minimizes unwanted resonance, allowing for a purer sound reproduction.

Expandable Options

For those looking to customize their setup further, the E-3000 includes two expansion slots for option boards. This feature allows users to enhance the amplifier’s capabilities, ensuring it remains relevant as audio technology evolves.

I made short movies with my stuffed animals as a kid, since then I knew from a young age I wanted to be a videographer. My parents always said I had a great eye for video/photo, so I made my job out of it. Now I make professional corporate video's. I love to learn all about new gadgets and electronics that come to the market, that's why I write/edit for "Best Of High End".
