High-Quality Integrated Amplifier with Digital Inputs

Yamaha A-S701 is a top-tier solution for anyone seeking clean, powerful, and musically authentic sound. Enhanced with the iconic ToP-ART (Total Purity Audio Reproduction Technology), this amplifier delivers an impressive level of performance with a focus on precision, dynamics, and natural sound reproduction.

High Power and Precise Power Supply

With a power output of 2 x 100W RMS (8Ω) and up to 160W under peak load, the A-S701 effortlessly drives various speakers—from compact models to serious floor-standing ones. Thanks to high-quality components like a custom transformer, aluminum heat sinks, and 12,000 μF capacitors, the sound remains clean even at high volume levels.

Digital Connectivity and Bluetooth Capabilities

The digital inputs (optical and coaxial) allow direct connection to a TV, Blu-ray player, or gaming console, ensuring crystal-clear signal transmission without degradation. You can also use the YBA-11 Bluetooth adapter (sold separately) for wireless music playback with aptX® quality. For audiophiles who appreciate analog sources, the A-S701 offers a Phono MM input for vinyl records, as well as CD Direct Amplification—a special mode that directly routes the signal from the CD source for maximum signal-to-noise ratio.

Pure Direct and Enhanced Sound Control

Pure Direct mode bypasses all unnecessary circuits for maximum signal purity. The analog control with continuously variable Loudness maintains the full frequency range even at low volume levels.

Connecting More Speakers

Ability to connect two pairs of speakers (A/B) and a subwoofer output make the A-S701 a versatile choice for various configurations and full-bodied bass.

Design and Standby Mode

Elegant design with an aluminum front panel and LED indicators is complemented by a practical remote control that also supports Yamaha CD players. Auto Power Standby function automatically turns off the amplifier after a period of inactivity, saving energy.
