Audiophile Features, 2x DSD USB DAC, Built-In Phonostage, Premium Build-Quality Just the Beginning of Yamaha A-S801 Integrated Amplifier
High-Resoultion Digital Audio Made Easy: Versatile Yamaha A-S801 Integrated Amplifier Includes ToP-ART, High-Performance 32-Bit DAC, and Pure Direct Mode for Stellar Sound
The Yamaha A-S801 integrated amplifier bulges with audiophile features and premium build-quality. Its divine sound comes courtesy of the Japanese company's Total Purity Audio Reproduction Technology concept, which emphasizes simple signal transmission for optimal fidelity. A double-bottom chassis eliminates vibrations, high-grade parts ensure sonic integrity, and a 2x DSD-capable USB DAC handles high-resolution audio. That's right: Just connect a USB cable from your computer to A-S801 and relish DSD, 2x DSD, and 24-bit/384kHz PCM audio. A-S801 even comes with a built-in MM phonostage and subwoofer terminal. Augmented by our 60-Day Satisfaction Guarantee, A-S801 is game, set, and match.
Circuit Design Based on ToP-ART (Total Purity Audio Reproduction Technology) Concept
ToP-ART Design and ART Base ensure optimum sound when processing and transmitting the audio signal. The signal is simple and direct, and therefore less likely to be affected by noise and distortion. The left and right channels are organized in a straight, symmetrical layout for the highest signal purity.
Strong Chassis Contributes Yields High-Density Sound and Pure Audio Reproduction
In order to effectively dampen the vibrations that have adverse effects on sound quality, A-S801 touts a chassis with a double-bottom design and 1mm iron plate. In addition, the power transformer and heat sinks in the power amp section are supported by an extremely strong and stable ART (Anti-Resonance and Tough) base. A solid center bar further enhances high rigidity and dampens vibrations.
High-Quality Parts Translate to Outstanding Performance
A custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, one point grounding system, extruded aluminum heat sinks, and other top-quality parts effortlessly handle demanding audio conditions. The quality of each individual part, as well as how they work together, determines the sound quality of this stellar component.
USB DAC Supports Native DSD (2.8MHz/5.6MHz) and PCM (384kHz/32-bit) Resolutions
A-S801's USB DAC supports native DSD (2.8MHz and 5.6MHz) and PCM (384kHz/32-bit) resolutions. This function also allows for direct connection to PCs for playback of the highest-resolution audio content offered today. The Yamaha-developed USB device controller has its own master clock that eliminates PC jitter, while a low-loss, high throughput ASIO 2.3 Yamaha Steinberg USB driver rounds out the section. During playback, indicators on the front panel clearly show which sampling frequencies are currently being used.
Stellar High-Performance 32-Bit D/A Converter
A 32-bit, two-channel SABRE Premier Audio DAC from ESS Technology delivers high-precision processing power and the ability to handle large amounts of audio data with full PCM 384kHz and native DSD 5.6 MHz. Since the built-in D/A converter generates its own master clock, an original jitter elimination function is included, permitting D/A conversion with an extremely low jitter. A two-channel D/A converter is also housed inside the chip to apply a double differential operation. The result: Exceptional high-performance and high-quality signal output, with a superior signal-to-noise ratio.
Digital Audio Input for TV and/or Blu-ray Disc Player
A-S801 is equipped for digital audio with an optical and digital coaxial input terminal. The optical is for receiving audio from a TV and the coaxial for receiving audio from a Blu-ray player. The audio stays in the digital domain, giving you pure, pristine, and dynamic sound.
CD Direct Amplification and Pure Direct Mode
With a straight connection to the CD input, CD Direct Amplification maximizes the CD source's signal-to-noise ratio. Additionally, engaging Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp as well as the tone, loudness, and balance controls to virtually eliminate any signal degradation.
Continuous Variable Loudness Control
A-S801 features a new analog loudness control on the front panel that uses electronic volume for higher sound quality and that lets you adjust the loudness effect as desired. Separate from the overall volume, it controls the balance of the low and high frequencies, providing full tonal range at any volume level by compensating for the natural loss in the human ear at soft levels.
Speaker A, B or A+B Selection, Gold-Plated Speaker Terminals, and a Subwoofer Terminal
You can connect two separate speaker systems and hear them in different rooms at the same time. Gold-plated speaker and input terminals supply a high-quality connection that prevents signal loss. A terminal for connecting a subwoofer is even provided, allowing you to increase the bass output of your system.
Rotary Encoder Input Selector, Connection for YBA-11 Bluetooth Wireless Adapter
A rotary encoder makes it quick and easy to select input sources. LEDs clearly show which source is selected, so you can easily switch sources in a dark room. And, with the YBA-11 Bluetooth Wireless Adapter, you’ll be able to stream music wirelessly from Bluetooth-compatible devices. Thanks to the digital coaxial connection and the aptX audio coding algorithm, you’ll enjoy wireless music streaming with optimum sound quality. You can also conveniently power the YBA-11 via the DC out connection on the rear panel of the amplifier.
