Product Description

Yamaha A-S801 Integrated Stereo Amplifier has advanced ToP-ART circuitry, a highly stable construction which delivers an energetic sound with increased musicality. It fully supports the latest high-resolution sound formats by incorporating advances like USB DAC function.

High Strength Chassis

A-S801 chassis has a double bottom with a 1mm iron plate to effectively dampen the vibrations that adversely affect sound quality. 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. The rigidity of this amplifier is further guaranteed by the inclusion of a solid centre bar and thus reducing vibration. These innovations of Yamaha's contribute to superior Signal-to-Noise ratio and a natural, rich sound reproduction.

ToP-ART concept

Based on a ToP-ART Design (Total Purity Audio Reproduction Technology) and ART Base ensures the optimum sound processing, and transmission of the audio direct, thereby reducing any unwanted noise and distortion. Yamaha’s ToP-ART technology features a Direct Symmetrical Design for the input to the output, with the left and right channels organised in a straight, symmetrical layout to ensure high signal purity.

High-Quality Parts

With a custom-made power transformer, custom-made block capacitors, one point grounding system, two direct speaker relays, with aluminium extruded heat sinks and other top-quality parts ensure this amplifier can effortlessly handle demanding audio signal conditions. The individual quality of each component, and how they communicate with each other, basically determines the sound quality of any component. As a consequence, Yamaha's ethos is to use only the very best high-quality parts, that they have carefully selected and tested.

Greater Sound Purity

Continuing on the idea to keep signal connections as direct as possible the CD input is a direct connection, and the CD Direct Amplification maximises CD source Signal-to-Noise ratio. Alternatively, the signal can be improved even further by engaging the Pure Direct mode which causes the signal to travel the shortest route along the circuit route, thereby bypassing the buffer amplifier and the controls for loudness, tone, and balance which virtually eliminates any signal degradation for the purest sound quality.

Continuously Variable Loudness

With an all new analogue loudness controller, that utilises an electronic volume control, the result is top sound quality signal, that lets you adjust the effect of loudness as you desire. Separated from the overall volume, this controls the balance of the low- and high-frequency harmonics, thus providing the spectrum at any volume level, compensating for the natural loss in the human ear of high and low frequencies at low intensities.

USB DAC Function

This supports 2.8MHz/5.6MHz DSD native resolution and PCM 384kHz/32-bit reproduction. A built-in USB DAC function allows direct connection to a PC and reproduction of today's popular high-resolution sound sources. Yamaha's own design USB device controller has its own master clock that maintains the timing and eliminates and PC jitter that can occur with high-resolution signal transmission.

The ASIO2.3 Yamaha Steinberg USB driver achieves lower delay and higher throughput. By offering compatibility with the 5.6MHz DSD format and PCM 384kHz/32-bit PCM files, you can access a wide range of high-resolution signals for superior high-quality sound. In addition, an indicator on the front panel displays easily understandable DSD and PCM playback formats and sampling frequencies.

High-Performance DAC

The DAC employed in this amplifier is from ESS Technology (ES9010K2M), which has been selected based on all its points; which is not only based on its high precision processing of 32-bit signals, but also the ability to handle large amounts of audio data with full PCM 384kHz, DSD 5.6MHz reproduction.

To minimise any impact of clock jitter, the DAC has its own master clock, and an original Jitter Elimination function. Furthermore, with a 2-channel DAC housed inside the chip, it applies double differential operation; the result is exceptionally high performance levels and high-quality output signals with superior signal-to-noise ratio.

Digital Audio Inputs

This amplifier is fully equipped for digital signals with both coaxial and optical inputs. The optical is for receiving audio from a TV, and the coaxial for receiving audio from a Blu-ray player. By keeping the audio signal in the digital domain, you hear a clean dynamic sound from all your entertainment sources, from sports events, regular Television programs, to movies, and concerts.

Connection for YBA-11

With the YBA-11, you will be able to stream music from a smartphone via Bluetooth or a PC to the Network receiver. As a consequence of employing Bluetooth aptX you can enjoy wireless streamed music with optimum sound quality. For your convenience, the YBA-11 can by charged via the DC-out connection on the rear panel of the amplifier.

Speaker Terminals

To support multi-room listening this amplifier includes four speaker terminals, so you can connect two separate speaker systems in different rooms and with a simple button you can switch between them or have them playing together. 

Subwoofer & Phono MM

By including a sub-woofer output allows you to increase the bass of your system for a more powerful sound with better overall sound quality. You can connect a turntable with an MM phono cartridge to play vinyl records, and you can enjoy analogue vinyl recordings from an amplifier with the latest digital/analogue technology.

Furthermore including gold plated terminals, for the inputs and the loudspeakers ensures a top quality connection that minimises and signal loss.  and input terminals.

Simple yet Sophisticated

With a beautifully simplistic and unique design which is inherited from Yamaha’s Hi-Fi audio components, this amplifier looks great and has a button layout that makes operating the amplifier very easy. The aluminium front panel of the A-S801 has a richly textured silver hairline finish, which gives it a sophisticated clean look. For the control knobs Yamaha use the same luxurious construction as you would find on their top of the range models.

Clean, Simple Design

By keeping the design of the remote control clean and simple ensures you can operate it easily with one-hand. The easy-to-use design makes it simple to adjust song volume and order. The unit has a sophisticated looking hairline finish that matches the design of the amplifiers. You can also use the remote to control a Yamaha CD player.

Rotary Encoder Selector

With the rotary encoder it becomes quick to select input sources. Plus, the luxury hairline finish material offers a nice tactile feeling. LEDs clearly show which source is selected, so you can easily switch sources even in a dark room.

Auto Power Standby

The amplifier has a power management function that detects when it has not been used for some time, approximately 8 hours and even though the power has been on the amplifier automatically shifts the unit into standby mode. Therefore, even if you forget to turn the amplifier off after listening, power consumption will be minimised.
