Yamaha R-N803: Fully equipped stereo receiver (2024)

A striking example of the symbiosis of the latest technological solutions and the classic approach in both circuitry and design is the Yamaha R-N803 stereo receiver.By combining in one package an integrated amplifier using discrete elements, an FM tuner and a multimedia network player that supports the proprietary MusicCast technology for building multi-room systems, Yamaha has offered an almost ideal component around which a modern music system can be built.

The Yamaha R-N803 is the first networked Hi-Fi receiver to feature YPAO™ (Yamaha Parametric room Acoustic Optimizer) technology previously reserved for high-performance home theater components.YPAO adjusts the speaker response to produce the best sound for the specific room in which the R-N803 will be used.YPAO delivers studio-quality audio performance by automatically correcting for the effects of less-than-ideal speaker placement and acoustic characteristics that differ from ideal rooms.

In addition, YPAO-RSC (YPAO – Reflected Sound Control) makes music sound clear and crisp by adjusting and compensating for unwanted sound reflected from nearby surfaces.Human hearing is less sensitive to high and low frequencies at low volumes.The YPAO Volume function is based on the use of automatic loudness compensation – adjusting the levels of high and low frequencies to changes in volume.Using measurements taken by the YPAO system, loudness compensation is optimized for your audio system settings and listening environment.

The central place on the front panel of the Yamaha R-N803, made of metallized plastic that skillfully imitates brushed aluminum, is given to a large information display.Below it, like soldiers in a guard of honor, lined up flat knobs for tone controls, channel balance and loudness.To the left of them is a rotary input switch, and to the right is a joystick for navigating the system menu.With its help, it is convenient to scroll through the lists on the display and select any item from them, be it a menu section or a music track.There is also a large volume control, a Pure Direct button, a USB port for quickly connecting external drives, a speaker switch and a headphone output.

You can integrate the Yamaha R-N803 into a computer network either via an Ethernet connection or wirelessly – a Wi-Fi adapter that supports the fastest 802.11n protocol today is built into the device.To use wireless communication, you just need to remember to connect the included antenna to the socket on the rear wall of the case.If the device is integrated into a computer network, then in addition to playing music from DLNA network servers, it also offers several additional functions.Firstly, receiving programs from Internet radio stations, of which there are already more than 20 thousand in all corners of the planet.For ease of navigation, they can be organized by genres, titles, regions and other criteria.Secondly, the receiver fully supports Yamaha MusicCast proprietary technology for creating multi-room systems, which allows you to combine various audio devices – multi-channel and stereo receivers, wireless speaker systems, sound bars, mini-systems, smartphones, tablets and computers – for joint operation.

This integration makes it possible to use a single music library for the entire system with central or distributed storage of audio files and centralized playback control using a special MusicCast Controller application installed on your smartphone or tablet running iOS or Android.Not only home network servers or the memory of your portable gadget, but also music streaming services on the global web like Spotify can serve as a storage for audio tracks.In addition, in the MusicCast system you can broadcast music from any source connected to one of the network nodes to different rooms of your house or apartment.For example, a vinyl record played on a Yamaha R-N803-based stereo system in the living room can be listened to on a Yamaha WX-020 wireless speaker system installed in the bedroom.

MusicCast technology is fully compatible with high-resolution audio – supporting FLAC, WAV formats up to 24-bit / 192 kHz, as well as DSD.The support for various wireless data transmission channels is also noteworthy, which greatly expands the choice of components for your multiroom system.MusicCast technology can use not only a Wi-Fi network, but also Bluetooth as a wireless data transmission medium.In addition, you can connect system components with regular twisted pair cables via Ethernet.Finally, you can stream music from your mobile phone or tablet directly to the receiver – either via Bluetooth using the A2DP protocol, or via Wi-Fi via AirPlay.It is possible to play audio files from external drives with a USB interface.

Digital-to-analog conversion is entrusted to the SABER 9006AS 192 kHz / 24-bit DAC chip, capable of processing not only a PCM stream with 24-bit / 192 kHz parameters, but also material in the DSD format.The output stages of the receiver are made using pairs of transistors A1695 / C4468 from Sanken.To cool them, a cast finned radiator is used, which occupies a central place inside the receiver body.Power supply is provided by a large and heavy transformer from Bando.

Compatible sources include networked PCs and network attached storage devices with DLNA®, mobile devices with wireless Apple® AirPlay® or Bluetooth® and several streaming services including Spotify, Pandora®, Deezer, Napster, SiriusXM Internet Radio, TIDAL and numerous free Internet radio stations.The R-N803 also plays multiple high-resolution formats, including 192 kHz/24-bit FLAC, WAV and AIFF, and 2.8/5.6 MHz DSD.For use with legacy sources, the R-N803 has a dedicated phono input for adding a turntable.Two optical and two coaxial digital inputs connect CD players, Blu-ray Disc™ players and TVs.

On the patch panel, we note the presence of a Phono input for connecting a vinyl record player with an MM cartridge and the possibility of using an active subwoofer to implement a trifonic based on the Yamaha R-N803.The power supply contains a power transformer that provides a maximum power of 140 W at 8 ohms, and the included remote control is used to control the stereo receiver.
