Description
RS151
With an 8-core CPU, Full HD touchscreen, and groundbreaking sound engineering, the RS151 delivers unparalleled clarity, precision, and immersive playback for the ultimate Hi-Fi experience. Featuring the advanced RoseOS operating system, the RS151 makes an easy partner for any high-quality audio system.
RS151 is a reference-level network streamer, using next-generation technologies. Boasting a full-HD touch screen within a sturdy aluminium construction, it serves as an ideal streamer for your music, and as a high-quality DAC for any other digital sources you may have.
Signal Processing
The RS151 makes use of Rose’s Digital Processing Core (DPC) Module, which was originally developed for the RD160 DAC.
This module precisely synchronizes any digital signal the DAC receives with the high-precision Femto clock as an I2S signal. It applies clock synchronization and locking processes to minimise jitter, allowing for accurate processing and a natural, clear sound performance.
By isolating this module away from the wider CPU circuitry, it’s possible to eliminate signal distortion and interference that’s generated within the unit from the digital signal path. The result is accurately processed data, resulting in a natural and clean sound across a wide range of digital formats.
DAC
The DAC design employed within the RS151 makes use of the leading ES9039PRO DAC chip with fourth generation Hyperstream® technology.
Within this section, the digital and analogue signal paths are completely separated, ensuring that each circuit operates independently and with reduced interference. The result is a more precise soundstage with excellent channel separation and beautiful imaging.
High-End Sound
RS151 makes use of advanced design principles and premium components to enhance sound quality. In the DAC stage, I/V conversion circuit and the Op-Amp stage, high-precision MELF resistors and WIMA film capacitors are used for improved linearity and minimised distortion.
A single-point ground design reduces grounding loops and suppresses noise and interference, and the advanced power supply design strengthens power stability and filters high-frequency noise. The result of this design is a set of remarkable measurements, highlighting the sonic clarity of the RS151.
The analogue stage of the RS151 also makes use of Rose’s new Noise Reduction Analog (NRA) filter, which the company designed to further eliminate noise and deliver an extremely flat response across the frequency range – even in the lower ranges.
Rose OS
At the centre of the RS151 is ROSE OS, HiFi Rose’s Android-based operating system, which opens a world of music and video to your streamer.
,p>ROSE OS supports local network music playback within Rose’s Music app, as well as CD playback and ripping via a connected optical drive. There is also support for internet radio, Spotify Connect, Tidal, Qobuz and Apple Music.
The RS151 is also Roon Ready and Plays with Audirvāna certified. In addition, the operating system offers support for video playback, either locally or within the Tidal or Rose Tube apps.
