The RS151 is a network streamer that achieves groundbreaking improvements in every aspect. ROSE's proprietary cutting-edge technologies developed during the RD160 project, combined with the latest flagship DAC chip and premium components, deliver revolutionary advancements in audio performance.
The significantly enhanced processing power, based on a next-generation 8-core CPU, integrates seamlessly with the Full HD wide-view multi-touch display introduced in the RS130, delivering a smoother and more enjoyable playback experience. With upgrades in performance, functionality, and convenience, the RS151 sets a new standard for high-resolution audio and streaming.
Advanced DAC Design with Ultra-Low Noise and Distortion
The DAC stage is equipped with the flagship ESS Technology ES9039PRO DAC chip. Utilising the 4th generation Hyperstream® technology, the ES9039PRO combines with a high-precision Femto clock to dramatically reduce jitter, and enhances linearity in the digital-to-analogue conversion process. The digital and analogue signal paths as well as all 8 channels are physically separated, ensuring that each circuit operates independently within their respective circuits.
This ensures the digital signal is transmitted to the analogue stage without being affected by noise or jitter from the digital circuitry, maintaining optimal accuracy and channel separation, resulting in excellent channel separation, precise staging, and rich three-dimensionality.
ROSE DPC(Digital Processing Core)™ Module
The RS151's digital stage applies the ROSE DPC™ module, which synchronises the incoming signal with a high-precision Femto clock and aligns it into an I²S signal, minimising jitter and maximising signal quality. This module is designed to ensure that all processing blocks maintain the highest accuracy of the signal. It completely separates the circuits for the user interface and GUI configuration from the digital audio signal path, thoroughly eliminating signal distortion and interference. With this design, the RS151 ensures precise signal processing, natural and clean sound, and compatibility across various digital formats.
Sound Quality Progress through Sophisticated Design
The RS151 incorporates advanced technologies and premium components to elevate sound quality. High-precision MELF resistors and audio-grade WIMA film capacitors in the DAC, I/V conversion, and OP-AMP stages enhance linearity and minimise distortion, while precisely controlled OP-AMP bias voltage ensures a refined, natural sound. A single-point ground design eliminates grounding loops and suppresses noise, and low-ESR, high-ripple decoupling capacitors stabilise the power supply by filtering high-frequency noise. These innovations enable the RS151 to achieve remarkable measurement values, with a SNR of 131.4dB and THD+N of 0.0002%, marking a breakthrough in signal accuracy and sonic performance.
ROSE NRA(Noise Reduction Analogue)™ Filter
The analogue stage features the ROSE NRA™ filter, designed to eliminate noise and enable flat frequency characteristics even at extremely low frequency ranges. With this innovation, the RS151 boasts a fixed frequency response across the entire range without roll-off, faithfully and clearly reproducing the original sound information embedded in high-resolution audio sources.
Enhanced Processing with Next-Gen 8-Core CPU
The RS151 features the next-generation 8-core CPU RK3588, offering a 4x increase in information processing performance and an 8x boost in graphics performance compared to its predecessor. In addition, the DRAM capacity has been upgraded from 4GB to 8GB, and the eMMC storage has been expanded from 8GB to 32GB, resulting in a processing speed that is more than twice as fast. This allows for smooth playback of large audio files as well as 4K high-resolution videos in HDR, while the media library capacity has grown by approximately three times, supporting over 1 million tracks.
