Yamaha R-N803 Network ReceiverYamaha
Experience the legend, enjoy the musicality
Yamaha boasts over 60 years of history as an audio brand. And the technology of R-N803 comes directly from Yamaha’s legendary Hi-Fi design concept ToP-ART (Total Purity Audio Reproduction Technology), which faithfully maintains the integrity of the audio by combining a meticulously symmetrical left / right circuit layout and signal directness (straightest, shortest signal paths) with a low-vibration chassis of high rigidity, equipped with the special resin frame “Art Base” that absorbs and blocks unnecessary vibration. It maintains sonic purity and accurate stereo image of the music to create unshakeable drivability.
The R-N803 uses the renowned SABRE 9006AS 192 kHz / 24-bit DAC (from ESS technology) to deliver superior S/N performance. Combined with Yamaha’s original network module, the unit thoroughly draws out all the sonic merits of high-resolution sound sources, effectively reproducing even the subtle ambience of concert halls and delicate expressive nuances in the sound.
Optimised for the ultimate
For the first time in a Hi-Fi receiver, the R-N803 is equipped with the Yamaha Parametric room Acoustic Optimiser (YPAO), a famed technology used in Yamaha's AV receivers. It measures the shape of the room, the material of the wall and the position of the speaker, and then automatically adjusts the sound to create the ideal response and sonic quality. The unit also features other advanced YPAO functions, including YPAO™-R.S.C (Reflected Sound Control), which actively corrects the important early reflection sounds that greatly influence sound quality, and YPAO Volume, which applies exceptionally high-precision EQ (equalisation), with 192 kHz / 64-bit operation. The result? You can create an ideal listening environment right in your home, just like that of a professional audio listening room.
Sophisticated circuit design
The power amp block adopts a symmetrical and direct circuit layout based on the ToP-ART concept, featuring a parallel push-pull structure using a total of eight bipolar type power transistors (four each, on left and right) as its output terminals. And by minimising the lengths of the audio signal paths in the circuit design, we’ve lowered impedance to achieve superb drive power with a maximum output of 145 watts (per channel).
