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.

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.
