HiFi Rose RS151 High Performance Network Streamer at Vinyl Sound Buffalo, NY USA

The RS151 is the flagship network streamer and DAC from HiFi Rose (Seoul, South Korea), available at Vinyl Sound in Buffalo, New York, USA. Built around ESS Technology's top-tier ES9039PRO DAC chip combined with HiFi Rose's proprietary ROSE DPC (Digital Processing Core) module and a high-precision Femto Clock, the RS151 achieves a signal-to-noise ratio of 131.4 dB (balanced) and a dynamic range of up to 150 dB with a CCITT filter. Housed in a precision-machined solid aluminum chassis, the RS151 features a 15.4-inch Full HD IPS LCD touchscreen, a built-in toroidal linear power supply, native DSD512 and PCM 32-bit/768 kHz support, MQA certification, HDMI eARC input, and balanced XLR outputs at 9.0 Vrms for seamless integration into reference two-channel systems.

ES9039PRO DAC, ROSE DPC Module, and Femto Clock

The ES9039PRO from ESS Technology represents the current summit of the SABRE DAC family, delivering the lowest noise floor and highest resolution available in a single-chip converter. In the RS151, it is paired with HiFi Rose's ROSE DPC module, which synchronizes all incoming digital sources to a high-precision Femto Clock before processing, minimizing jitter from USB, optical, coaxial, AES/EBU, and HDMI eARC inputs. The balanced XLR analog output delivers 9.0 Vrms, and the unbalanced RCA output delivers 4.5 Vrms. Stereo crosstalk measures a maximum of -143 dB across the full 20 Hz to 20 kHz range, and frequency response extends to 75 kHz within +/-0.5 dB. The RS151 is MQA-certified and supports native playback of DSD512 (22.5792 MHz), PCM at up to 32-bit/768 kHz, making it fully compatible with the highest-resolution content from TIDAL, Qobuz, and local file libraries.

Full-Width 15.4-Inch Touchscreen, Toroidal Linear PSU, and Versatile Connectivity

The RS151 matches its reference-grade electronics with a precision-machined solid aluminum chassis that minimizes vibrations and electromagnetic interference. The 15.4-inch Full HD IPS LCD touchscreen (1920 x 382 resolution) runs HiFi Rose's customized Android 12-based Rose OS on an octa-core RK3588 CPU with 8 GB of LPDDR4X RAM and 32 GB of eMMC system storage, providing smooth operation of the interface and the streaming platform simultaneously. A built-in toroidal linear power supply ensures ultra-low noise and high current stability, contrasting with the switched-mode supplies used in less expensive network players. Input connectivity includes optical, coaxial, AES/EBU, HDMI eARC, and USB-B, while outputs include optical, coaxial, balanced XLR, unbalanced RCA, AES/EBU, I2S-HDMI, and HDMI 2.0 video at 4K/60 Hz. Wired Gigabit Ethernet and optional Wi-Fi via USB dongle, plus Bluetooth 5.4 with aptX, cover all network connectivity requirements. The RS151 is controlled via the included IR remote control or the ROSE Connect app for iOS and Android.

Technical Specifications

Frequently Asked Questions

What is the HiFi Rose RS151?

The HiFi Rose RS151 is the flagship network streamer and DAC from Seoul, South Korea, featuring the ESS ES9039PRO DAC chip, a high-precision Femto Clock, a 131.4 dB SNR (balanced), a built-in toroidal linear power supply, native DSD512 and PCM 32/768 support, HDMI eARC input, and a 15.4-inch Full HD touchscreen. It is Roon Ready, MQA certified, and available at Vinyl Sound in Buffalo, New York, USA.

How does the RS151 compare to the Aurender N200?

The HiFi Rose RS151 and the Aurender N200 (from Seoul, South Korea) both target serious audiophiles in the flagship network player category. The Aurender N200 is a transport-only device requiring an external DAC, whereas the RS151 integrates the ES9039PRO DAC and delivers 9.0 Vrms balanced output directly to a preamplifier or power amplifier. The RS151 includes a 15.4-inch touchscreen for in-room control and video playback, while Aurender relies primarily on the Conductor app. The RS151's toroidal linear PSU and ROSE DPC Femto Clock target the same low-noise, low-jitter goals as the N200's solid-state drive and linear PSU architecture, but the RS151 offers a complete source solution in a single chassis.

What is the ROSE DPC module?

The ROSE DPC (Digital Processing Core) module is HiFi Rose's proprietary digital signal management system. It accepts digital audio from all inputs, synchronizes the signal to the internal Femto Clock, and converts it to I2S format before passing it to the DAC chip. The GUI and user interface circuitry are completely isolated from the audio signal path within the DPC module, eliminating a common source of digital interference. This architecture ensures that the ES9039PRO DAC receives a precisely timed, interference-free signal regardless of input source.

Can the RS151 stream from a NAS drive?

Yes. The RS151 supports NAS drive access via SMB, FTP, and WebDav network protocols over its Gigabit Ethernet or Wi-Fi connection. It also accepts a 2.5-inch internal SSD, a Micro SD card, and external USB storage devices, and can build a local media library from all these sources simultaneously. The RK3588 CPU and 8 GB of RAM allow the library to grow to over one million tracks while maintaining a fast, responsive interface.

Does the RS151 work with Roon?

Yes, the RS151 is fully Roon Ready certified, appearing as a Roon endpoint on the network and accepting streaming audio and metadata from a separate Roon Core. It is also MQA certified for TIDAL Masters playback, Spotify Connect compatible, and supports AirPlay and DLNA/UPnP.
