Hi-Fi Rose RS151 Network Streamer

The Next Generation

The 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. The advanced Rose OS operating system makes the RS151 an easy partner for any high-quality audio system.

Innovative 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.

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. 

Engineered for Sound

The 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. 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.

ROSE Audio Engine

As well as ROSE OS, the RS151 also makes use of the ROSE Audio Engine, an in-house development that ensures all digital audio is delivered to the DAC without loss for precise signal processing.

The upgraded 8-Core CPU used in the RS151 boasts four times the data processing performance and eight times the graphics performance of anything that has come before it in the Rose range. The result of this upgrade is the best ROSE OS experience yet, including support for larger music libraries and audio or video files.

Connect what you need

The RS151 is designed to be an ideal entertainment hub. With a wide range of connections, including HDMI eARC, Hi-Res Coax, AES/EBU and USB inputs and outputs, Optical inputs and outputs, I2S output and an analogue line input, it’s easy to integrate into almost any audio system. There’s also a new external Bluetooth module and antenna, supporting Bluetooth® v5.4 via an advanced Qualcomm chipset, for premium wireless audio playback from a connected device.

Sound Design

The RS151’s chassis is crafted from aluminium plates up-to 30mm thick, CNC-machines for effective heat dissipation, ensuring stable performance even during extended use. Its minimal assembly joints enhance structural rigidity, effectively suppressing vibrations. The result is an ideal chassis with an appealing aesthetic.

Similarly, the new Full HD 15.4” display has a wide viewing angle and superior resolution, adding to the overall aesthetic. The intuitive multi-touch panel, alongside the supplied IR remote control and the full-feature ROSE Connect application, mean setting up and living with the RS151 is always a pleasure.

The RS151 redefines network streaming, combining groundbreaking digital processing, state-of-the-art DAC design, and user-friendly enhancements. With unparalleled sound quality, seamless operation, and next-generation connectivity, it delivers an unmatched Hi-Fi experience for audiophiles and enthusiasts alike.
