High Performance Network Streamer Gen2 RS151

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 sophisticated design, 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.

INNOVATIVE SIGNAL PROCESSING

ROSE DPC (Digital Processing Core)™ Module

The ROSE DPC™ module is applied to the RS151’s digital stage, minimizing jitter and maximizing signal quality by precisely synchronizing input signals with a highly precise Femto clock and aligning them as I²S signals. All processing blocks within this module are designed to maintain the highest level of signal accuracy. Additionally, the circuit for the user interface and GUI configuration is completely isolated from the digital audio signal path, thoroughly eliminating signal distortion and interference. Through this design, the RS151 guarantees accurate signal processing, natural and clean sound, and seamless compatibility with various digital formats.

CUTTING-EDGE DAC DESIGN

4th-Hyperstream® Technology

Featuring 4th-generation Hyperstream® technology, the ES9039PRO combines with a highly precise Femto clock to drastically suppress jitter. In addition, it further enhances linearity during the digital-to-analog conversion process. This allows to deliver distortion-free, clean sound with improved timing accuracy and precise reproduction of detailed acoustic nuances in high-resolution audio.

Complete Separation of Digital and Analog

The digital and analog signal paths are physically and completely separated, ensuring that each circuit operates independently. This design prevents any influence from noise and jitter generated in the digital circuit, offering a higher level of clarity and accuracy without interference or distortion between the paths.

8-Channel Independent Processing Design

The ES9039PRO features an independent processing design, ensuring that all 8 channels operate independently within their own dedicated circuits. This enables the delivery of exceptional channel separation, precise stereo imaging, an expanded soundstage, and outstanding spatiality without any channel interference.

ROSE NRA (Noise Reduction Analog)™ Filter

The analog 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.

RS151 vs RS150B
Refined. Faster. More Powerful.

Enhanced Signal Processing

Now featuring the ROSE DPC module and Femto clock, which were absent in the RS150B. This dramatically reduces jitter and improves timing accuracy, delivering a cleaner, more natural sound. DSD upsampling is now supported up to DSD512, where the RS150B had none.

Upgraded DAC & Audio Performance

The new ES9039PRO DAC replaces the previous ES9038PRO, with independent 8-channel processing instead of shared circuits. This improves stereo imaging and channel separation, while the signal-to-noise ratio jumps from 121dB to 131.4dB, lowering noise for even greater clarity.

More Power, Faster Performance

The new 8-core processor is 4x faster, while RAM has doubled to 8GB, and storage has quadrupled to 32GB. Now running Android 12, the RS151 is smoother, more responsive, and more capable than ever.

Larger Display & Better Connectivity

The touchscreen has increased from 14.9” to 15.4” and now features Full HD resolution for sharper visuals. Connectivity improvements include eARC for uncompressed HDMI audio, Trigger In/Out for external device control, and Bluetooth 5.4 with aptX for better wireless audio.

Smarter, More Refined Features

Unlike the RS150B, the RS151 includes PCM-to-DSD512 conversion for enhanced playback options. The IR remote control replaces Bluetooth for improved range and reliability, and COAX & AES/EBU support has been upgraded to PCM 384kHz and DSD128 for higher-resolution playback.
