Yamaha, a renowned name in the audio industry, has consistently delivered exceptional sound quality with its amplifiers. In this comprehensive review, we’ll dive into the Yamaha A-S501 Integrated Amplifier, exploring its features, performance, design, connectivity options, and overall value proposition. Let’s discover why the A-S501 stands out as a powerful and versatile addition to any audio setup.
Aesthetics and Build Quality
The Yamaha A-S501 boasts an elegant and minimalistic design that aligns with Yamaha’s commitment to aesthetics and functionality. The amplifier’s sturdy construction, including a reinforced chassis and anti-resonance feet, helps minimize vibrations, resulting in cleaner and more precise sound reproduction. The brushed aluminum front panel adds a touch of sophistication, making it a visually appealing addition to any audio setup.
Power and Performance
At the heart of the Yamaha A-S501 lies a robust power output capable of delivering 85 watts per channel (8 ohms, 20Hz-20kHz, 0.019% THD). This ample power allows the A-S501 to drive a wide range of speakers, from bookshelf models to floor-standing speakers, with ease. The amplifier’s ToP-ART (Total Purity Audio Reproduction Technology) design further enhances signal purity and fidelity, ensuring a clear and dynamic audio performance.
ToP-ART Technology
The ToP-ART design philosophy focuses on maximizing signal purity by minimizing the impact of unwanted noise and distortion. Yamaha achieves this by carefully selecting high-quality components and employing symmetrical circuit layout techniques. The result is an amplifier that faithfully reproduces audio signals, preserving the integrity of the original music.
High-Quality DAC and Pure Direct Mode
The Yamaha A-S501 features a high-performance DAC (Digital-to-Analog Converter), allowing users to connect digital audio sources such as CD players, media players, or computers directly to the amplifier. The DAC ensures precise and accurate digital-to-analog conversion, maintaining the sonic integrity of the audio signal. Additionally, the Pure Direct mode bypasses unnecessary circuitry and switches, enabling a more direct and unadulterated signal path for critical listening sessions.
Multiple Inputs and Outputs
The A-S501 comes equipped with a comprehensive set of inputs and outputs, providing flexibility for connecting various audio sources and devices. It features four analog RCA inputs, allowing users to connect a CD player, turntable (with a phono preamp), and other analog sources simultaneously. Additionally, there’s a dedicated MM (Moving Magnet) phono input for vinyl enthusiasts, ensuring an accurate and engaging vinyl playback experience. Furthermore, two sets of speaker outputs accommodate bi-wiring configurations or enable connections to two separate speaker pairs.
Subwoofer Output and Rec Out
For users seeking to augment their audio setup with deep bass, the Yamaha A-S501 provides a dedicated subwoofer output. This feature allows seamless integration of a powered subwoofer, enriching the overall listening experience with enhanced low-frequency reproduction. Moreover, the Rec Out functionality allows users to record audio from the amplifier’s inputs, offering added convenience for archiving favorite vinyl records or other analog sources.
Continuously Variable Loudness Control
The A-S501 incorporates a continuously variable loudness control, allowing users to optimize sound balance at lower listening volumes. The loudness control adjusts the tonal balance, compensating for the human ear’s reduced sensitivity to bass and treble frequencies at lower volume levels. This ensures that users can enjoy full-bodied and immersive sound even at lower volume settings.
Speaker A/B Selector
With its Speaker A/B selector, the Yamaha A-S501 offers the option to power two sets of speakers independently. This feature is particularly useful for multi-room setups or when users want to switch between different sets of speakers without constant reconfiguration.
Remote Control and System Connectivity
The amplifier comes with a user-friendly remote control, enabling easy adjustment of volume, source selection, and other settings from a distance. Moreover, the A-S501 offers system connectivity with other Yamaha audio components, allowing seamless integration and synchronized operation within a Yamaha-based audio setup.
