Key Features  

• 35W Class A Power: Delivers 35W per channel into 8 ohms, 70W into 4 ohms, and 140W into 2 ohms.  with pure Class A operation for warm, distortion-free sound and linear power delivery.  
• Balanced AAVA Volume Control: Features ANCC (Advanced Noise and Distortion Cancelling Circuit) for ultra-low noise and precise volume adjustment without signal degradation.  
• MCS+ Circuitry: Multiple Circuit Summation enhances signal purity, reducing noise for a transparent, detailed soundstage.  
• Ultra-High Damping Factor (1,000): Optimized MOS-FET switches and signal paths ensure precise control over speakers, delivering tight, articulate bass.  
• Robust Power Supply: Massive toroidal transformer and dual 33,000μF filtering capacitors provide stable, clean power for dynamic performance.  
• Fully Balanced Design: Balanced signal path from input to output minimizes interference, ensuring pristine audio with excellent 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 protects 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.  
• Elegant Design: Compact chassis with champagne gold panel, backlit VU meters, flip-down control door, and RC-250 remote for a luxurious, user-friendly experience.

Why Choose the Accuphase E-700?

The E-700 brings flagship-grade Class A performance to a compact form, drawing on technologies from Accuphase’s C-2300 preamplifier and A-48 power amplifier. Its Balanced AAVA and MCS+ circuitry deliver a noise-free, vibrant soundstage with exceptional clarity and warmth, ideal for discerning listeners. Users praise its rich, detailed sound and ability to drive complex loads, 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 handcrafted Japanese build quality, the E-700 offers reference-grade audio for smaller spaces, rivaling separates at a competitive price point.
