High-Power Amp
The R-N303 utilizes a high-power amp featuring a single push-pull and discrete configuration, delivering a maximum output of 140W per channel at 8 Ohms. Its low-impedance design helps maximize the lengths of the audio signal paths, while placing the power supply unit near the amp unit to help reduce energy loss, for enhanced sound reproduction with most speakers.
Low-Noise Circuitry Design
The R-N303 features circuitry designed to prioritize sound quality by dividing the analog and digital sections into separate blocks for low noise and an augmented S/N ratio.
Engineered for High Resolution
The R-N303 is compatible with high-resolution sound sources, such as DSD 5.6 MHz native and AIFF, WAV, FLAC 192 kHz/24-bit, as well as Apple Lossless 96 kHz/24-bit files. It uses a Burr-Brown 192 kHz/24-bit DAC to deliver enhanced S/N performance.
Low-Jitter Network Module
The network module contains a clock designed for high-precision, low-jitter performance to help improve the reproduction of high-resolution sound sources. Pure audio clock generation without an added jitter from the clock generator helps lower the creation of jitter noise when playing network and Bluetooth sources for further S/N enhancement.
Enjoy All Your Music Sources
The R-N303 lets you enjoy music from CD players and turntables, and it can play music you have stored on your computer or NAS (network-attached storage). You can also play music wirelessly from smartphones or tablets using Bluetooth or AirPlay, as well as a variety of music from streaming services and AM/FM radio.
MusicCast Expands Entertainment Possibilities
MusicCast can stream digital music content from your smartphone, PC, or NAS to other MusicCast devices in your home using your existing network. It can also share the music from external devices such as a CD player or TV connected to the R-N303. Audio content from Bluetooth-connected smartphones or tablets can also be streamed to MusicCast devices in multiple rooms.
Digital Audio Input for TV or Blu-ray Players
The R-N303 is equipped for digital audio with both optical and coaxial inputs. The optical is for receiving audio from a display, and the coaxial is for receiving audio from a Blu-ray player. The audio stays in the digital domain, helping to provide pure dynamic sound for all your entertainment sources.
