HiFi Rose RS151 Network Streamer

HiFi Rose RS151 Network Streamer at Vinyl Sound Toronto, Canada

The RS151 is a high-performance network streamer and DAC from HiFi Rose (Seoul, South Korea), available at Vinyl Sound in Toronto, Canada. Built around the ESS SABRE ES9039PRO DAC chip with 4th-generation Hyperstream technology, the proprietary ROSE DPC (Digital Processing Core) module with Femto clock, and an 8-core processor delivering four times the computing power of its predecessor, the RS151 achieves a signal-to-noise ratio of 131.4 dB and supports DSD upsampling to DSD512. Combining a 15.4-inch Full HD IPS touchscreen with balanced XLR and unbalanced RCA analog outputs, a full digital output suite including I2S HDMI, and HDMI eARC input, the RS151 sets a new benchmark for all-in-one network streaming in a single chassis. It is available in Canada through authorized HiFi Rose dealers including Vinyl Sound.

RS151 vs RS150B: A Generational Leap

The RS151 is not an incremental update to the RS150B. The ROSE DPC module and Femto clock are entirely new additions absent from the RS150B, as is DSD upsampling support which now reaches DSD512 versus none on the previous model. The DAC chip advances from the ES9038PRO to the ES9039PRO with independent 8-channel processing replacing shared circuits, and the signal-to-noise ratio improves from 121 dB to 131.4 dB. Processing power increases fourfold via the new 8-core CPU, RAM doubles to 8 GB, and internal storage quadruples to 32 GB. Connectivity gains include HDMI eARC for uncompressed audio, Trigger In and Out for system automation, and Bluetooth 5.4 with aptX.

Frequently Asked Questions

Q: What is the HiFi Rose RS151?
A: The HiFi Rose RS151 is a high-performance network streamer and DAC from HiFi Rose of Seoul, South Korea, featuring the ESS SABRE ES9039PRO DAC chip, the proprietary ROSE DPC module with Femto clock, a signal-to-noise ratio of 131.4 dB, DSD512 upsampling, an 8-core processor running Android 12, and a 15.4-inch Full HD IPS touchscreen. It is available in Canada through authorized HiFi Rose dealers including Vinyl Sound in Toronto.

Q: How does the HiFi Rose RS151 compare to the Aurender A200 and Lumin X1?
A: The HiFi Rose RS151 competes directly with reference-class streaming DACs including the Aurender A200 and Lumin X1. The Aurender A200 uses an AKM AK4191 and AK4499EX DAC combination with a quoted SNR of 130 dB and includes a built-in CD drive, but does not offer I2S output or PCM-to-DSD conversion. The Lumin X1 uses an ESS ES9038PRO in dual-mono configuration with a quoted SNR of 130 dB and supports fiber network input, but does not include a Femto clock or DPC module for jitter reduction. The RS151 differentiates itself with the newer ES9039PRO chip, a dedicated ROSE DPC module and Femto clock, DSD512 upsampling and PCM-to-DSD512 conversion, I2S HDMI output, HDMI eARC input, and a measured SNR of 131.4 dB that exceeds both competitors.

Q: What is the ROSE DPC module and what does it do?
A: The ROSE DPC (Digital Processing Core) module is a proprietary HiFi Rose circuit that acts as the signal processing hub between the network input and the DAC chip. It synchronizes all incoming digital audio signals to a Femto clock reference and converts them to I2S format before they reach the ES9039PRO. The DPC module also physically isolates the GUI and user interface circuits from the audio signal path, preventing the computational activity of the touchscreen and operating system from generating noise or jitter in the audio chain. This dual function of precision clock alignment and circuit isolation is the primary reason the RS151 achieves a 10.4 dB improvement in signal-to-noise ratio over its predecessor, the RS150B.

Q: Can the HiFi Rose RS151 upsample PCM to DSD?
A: Yes, the HiFi Rose RS151 supports both native DSD playback up to DSD512 and real-time PCM-to-DSD512 conversion. This allows standard PCM audio files, including CD-quality 16-bit/44.1 kHz content, to be converted to DSD512 on the fly before being processed by the ES9039PRO DAC. DSD512 operates at a sampling frequency of 22.5792 MHz, pushing quantization noise well above the audible range and delivering a smoother, more analog-like presentation favored by many high-resolution audio listeners.

Q: What makes the HiFi Rose RS151 better than the RS150B it replaces?
A: The HiFi Rose RS151 represents a fundamental redesign rather than a revision of the RS150B. Key improvements include the addition of the ROSE DPC module and Femto clock, an upgrade from the ES9038PRO to the ES9039PRO DAC with independent 8-channel processing, a jump in signal-to-noise ratio from 121 dB to 131.4 dB, DSD512 upsampling support where the RS150B had none, four times the processing power via the new 8-core CPU, doubled RAM, quadrupled internal storage, a larger Full HD display, HDMI eARC input, Trigger In and Out, and Bluetooth 5.4 with aptX.

Q: What amplifiers pair well with the HiFi Rose RS151?
A: The HiFi Rose RS151 is a complete streaming DAC with balanced XLR and unbalanced RCA analog outputs, making it compatible with any integrated amplifier or preamplifier. Its balanced XLR output pairs naturally with amplifiers such as the HiFi Rose RA180 or RA280, both of which accept balanced XLR input and are available at Vinyl Sound in Toronto. For listeners who prefer to use the RS151 purely as a transport, its I2S HDMI, AES/EBU, coaxial, optical, and USB digital outputs connect to virtually any outboard DAC on the market.

Q: Is the HiFi Rose RS151 Roon Ready?
A: The HiFi Rose RS151 runs Android 12 and supports a wide range of streaming platforms and protocols through the Rose Connect ecosystem. For the most current Roon Ready certification status of the RS151, prospective buyers are encouraged to confirm directly with Vinyl Sound, HiFi Rose's authorized dealer in Toronto, Canada, who can provide up-to-date compatibility information and arrange an in-store demonstration.

Q: Where can I buy the HiFi Rose RS151 in Toronto or Canada?
A: The HiFi Rose RS151 is available at Vinyl Sound, an authorized HiFi Rose dealer in Toronto, Canada. Vinyl Sound carries the complete HiFi Rose product range and provides in-store demonstrations, expert guidance on system matching, and authorized Canadian warranty support for all HiFi Rose products.
