Yamaha A-S501

Yamaha A-S501 Integrated Amplifier | Natural Sound with ToP-ART Precision

Pure, Dynamic, and Timeless Hi-Fi Performance

The Yamaha A-S501 embodies the company’s “Natural Sound” philosophy — delivering pure, uncolored, and musical reproduction through its advanced ToP-ART (Total Purity Audio Reproduction Technology) design. Every element of this amplifier is engineered to preserve sonic integrity from input to output.

High Sound Quality Circuit Design – ToP-ART & ART Base

At the heart of the A-S501 lies Yamaha’s ToP-ART design, featuring a direct symmetrical layout that minimizes signal loss and distortion. Left and right channels are organized in a perfectly balanced configuration for unmatched purity.
The ART (Anti-Resonance and Tough) Base and solid center bar enhance structural rigidity, suppressing vibration and maintaining rich, musical detail even at high volumes.

High-Grade Components for Superior Audio

From custom-made power transformers and block capacitors to gold-plated terminals and aluminum heat sinks — every part is carefully selected and tested for optimal performance. This meticulous component quality ensures effortless handling of complex audio passages and a warm, natural tone.

Built on Yamaha’s 125-Year Musical Heritage

Drawing on more than a century of craftsmanship in musical instruments and Hi-Fi design, Yamaha infuses the A-S501 with refined technology and timeless engineering. Built under the “Natural Sound” concept, it delivers music exactly as it was recorded — pure, expressive, and emotionally engaging.

Pure Direct Mode

For ultimate sonic transparency, Pure Direct mode routes the signal via the shortest possible path, bypassing the buffer amp and tone circuitry. The result: zero coloration and absolute sound purity.

Continuously Variable Loudness Control

The analog loudness control allows users to fine-tune tonal balance at any listening level, compensating for natural human hearing limitations. Enjoy full frequency range even at low volumes — with the clarity and depth Yamaha is known for.

Digital Audio Inputs for TV and Blu-ray Players

Equipped with both optical and coaxial digital inputs, the A-S501 integrates effortlessly into modern setups — preserving digital signal integrity for crystal-clear playback of music, movies, and more.

Wireless Streaming Ready

Connect Yamaha’s optional YBA-11 Bluetooth® adapter to stream music wirelessly from your smartphone, tablet, or PC. The digital connection and aptX® codec deliver high-resolution audio with minimal compression loss.

Flexible Speaker & Subwoofer Connections

With A, B, or A+B speaker selection and dedicated subwoofer output, the A-S501 easily powers dual speaker systems or multi-room setups. Add a subwoofer to extend low-frequency performance for a more impactful soundstage.

Phono MM Input for Vinyl Enthusiasts

A dedicated phono input allows seamless connection with turntables equipped with MM cartridges — bringing analog warmth and authenticity to your listening experience.

Elegant Design and Intuitive Control

The brushed aluminum front panel, precision rotary selector with LED indicators, and minimalist control layout reflect Yamaha’s timeless design language — functional, beautiful, and built to last.

Convenient Remote Control

The simple, ergonomic remote mirrors the amplifier’s design philosophy — intuitive, elegant, and compatible with Yamaha CD players for complete system control.

Energy-Saving Auto Standby

The A-S501 automatically switches to standby after 8 hours of inactivity, conserving power without compromising convenience.
