ROSE RS151

The ROSE RS151 is a second-generation high-end network streamer designed to deliver uncompromising audio performance, with significant improvements over previous models. It integrates proprietary technologies developed during the RD160 project, a state-of-the-art DAC, and a sophisticated design, resulting in a complete evolution of sound performance. The powerful next-generation octa-core CPU provides data processing speeds four times faster and graphics performance eight times higher, ensuring smooth playback of high-resolution audio files and 4K HDR videos, while supporting large music libraries with over a million tracks.

At the digital core of the RS151 is the ROSE DPC™ (Digital Processing Core) module, which minimizes jitter through a highly precise Femto clock and aligns signals as I²S. All processing blocks within the module are designed to maintain maximum signal accuracy, while the user interface and GUI are fully isolated from audio paths, eliminating interference and distortion. The DAC features a fourth-generation SABRE ES9039PRO chip with Hyperstream® technology and fully separated digital and analog paths, delivering extremely high SNR and optimal linearity. Independent eight-channel processing ensures exceptional channel separation, precise stereo imaging, and immersive soundstage, while high-quality components such as MELF resistors and WIMA film capacitors enhance linearity and reduce distortion. The ROSE NRA™ analog filter maintains a flat frequency response even at extremely low ranges, ensuring a natural and faithful sound.

The RS151 also stands out for its visual excellence and ease of use. Its 15.4-inch Full HD natural-size multi-touch display offers a wide viewing angle, vivid reproduction of album covers and videos, and intuitive interaction. Connectivity is enhanced with eARC for uncompressed 24-bit/192 kHz audio transmission, Trigger inputs and outputs for centralized control of external devices, Bluetooth 5.4 with aptX codec for high-quality wireless audio, and Hi-Res support on Coax and AES/EBU inputs, with PCM-to-DSD conversion up to DSD512 via upsampling. The IR remote replaces the previous Bluetooth control, providing greater stability and freedom of use without pairing.

The integrated Android 12 operating system improves user security and convenience, while 8 GB of DRAM and 32 GB of eMMC memory allow fast handling of large libraries and complex media files. The RS151 represents a total innovation in high-resolution audio streaming, combining processing power, signal precision, complete separation of digital and analog paths, high-quality components, and an engaging visual interface, delivering an immersive and natural audio experience down to every detail.
