Accuphase E-800S Integrated Amplifier

Product Description

The Accuphase E-800S Integrated Stereo Amplifier is the epitome of Class A amplification, delivering 50W per channel into 8 ohms, 100W into 4 ohms, and 200W into 2 ohms with a damping factor of 1,000 for unparalleled speaker control. As the flagship model succeeding the E-800, it features Balanced AAVA volume control with ANCC technology, a six-fold parallel push-pull power stage, and fully balanced circuitry, producing a warm, transparent soundstage with exceptional detail and dynamics. Encased in a luxurious champagne gold chassis with persimmon wood panels and large VU meters, the E-800S is a masterpiece of Japanese craftsmanship, ideal for audiophiles and home theater enthusiasts seeking reference-grade performance and timeless elegance.  

Key Features  

• Pure Class A Power: Delivers 50W per channel into 8 ohms, 100W into 4 ohms, and 200W into 2 ohms, ensuring linear, distortion-free sound across demanding speaker loads.  
• Balanced AAVA Volume Control: Advanced Noise and Distortion Cancelling Circuit (ANCC) minimizes noise for pure, precise volume adjustments without signal degradation.  
• Six-Fold Push-Pull Output: Six parallel push-pull bipolar transistors per channel, mounted on large heatsinks, provide high-current amplification for dynamic, effortless performance.  
• Ultra-High Damping Factor (1,000): Optimized MOS-FET switches with ultra-low on-resistance (1.6mΩ) deliver precise speaker control and tight, articulate bass.  
• Robust Power Supply: Massive toroidal transformer and dual 56,000μF filtering capacitors (112,000μF total) ensure stable, clean power for high-current demands. 
• Fully Balanced Circuitry: Balanced signal path from input to output eliminates interference, ensuring pristine audio with superior phase accuracy.  
• Versatile Connectivity: Includes 5 RCA line-level inputs, 2 XLR balanced inputs, pre-out/main-in, and optional boards (DAC-60 for digital, AD-60 for MM/MC phono, Line-10 for high-level input).  
• Advanced Protection: MOS-FET-based circuitry safeguards against short-circuiting, DC voltage, and overheating, ensuring reliability without relay contact resistance.  
• High-Quality Headphone Amp: Discrete-component headphone amplifier delivers powerful, detailed sound for private listening.  
• Luxurious Design: Champagne gold panel, persimmon wood side panels, backlit VU meters, flip-down control door, and RC-250 remote for a sophisticated, tactile experience.

Why Choose the Accuphase E-800S?

The E-800S distills Accuphase’s 50-year expertise into a flagship Class A amplifier, incorporating technologies from the C-3900 preamplifier and A-300 power amplifier. Its Balanced AAVA and MCS+ circuitry create a noise-free, vibrant soundstage with the warmth and richness unique to pure Class A, ideal for the most discerning listeners. Users praise its lush, detailed sound and ability to drive complex loads down to 2 ohms, though some note a slightly forward treble that benefits from careful speaker pairing. With a damping factor of 1,000, expandable connectivity via optional DAC and phono boards, and exquisite build quality, the E-800S delivers reference-grade performance rivaling high-end separates, perfect for compact, uncompromising hi-fi and home theater systems.
