HiFi Rose RD160 DAC at Vinyl Sound Toronto Canada

The RD160 is a flagship standalone DAC from HiFi Rose (Seoul, South Korea), available at Vinyl Sound in Toronto, Canada. Built around the AKM AK4499EX Velvet Sound Verita chipset paired with the AK4191EQ noise-shaper, the RD160 employs the proprietary ROSE CIM™ Completely Isolated Module architecture to achieve complete physical separation of digital and analog signal paths. Three independent custom reference linear power supplies, a high-precision OCXO clock, and the ROSE DPC™ digital processing module combine to deliver a measured SNR of 124 dB on both coaxial and XLR outputs, placing the RD160 firmly in reference-class DAC territory. The RD160 is the first dedicated DAC from HiFi Rose and is available in Canada through authorized dealers including Vinyl Sound.

ROSE DPC™ Digital Processing Core

The ROSE DPC™ (Digital Processing Core) module forms the foundation of the RD160's digital architecture. All incoming digital signals are synchronized to a high-precision OCXO clock and aligned as I2S signals before conversion, a process that is especially critical when handling high-resolution PCM and native DSD formats where even minute jitter artifacts degrade transient clarity and tonal purity. GUI and user interface circuitry is completely isolated from the audio signal path, eliminating any possibility of digital interference contaminating the music signal. The result is a digital stage that delivers consistently accurate, jitter-minimized output regardless of input source or format.

ROSE CIM™ Architecture: Complete Isolation of Digital and Analog

The ROSE CIM™ (Completely Isolated and Moduled) architecture takes standard DAC design significantly further. The AK4191EQ handles digital filtering and initial delta-sigma conversion, while the AK4499EX performs the final digital-to-analog conversion. Rather than placing these functions on a shared PCB, HiFi Rose physically separates digital and analog circuits onto dedicated mono boards, one per channel. This structural isolation achieves an SNR of 124 dB on coaxial and XLR outputs and eliminates the cross-contamination between digital switching noise and sensitive analog signals that limits performance in conventional single-board DAC designs.

Fully Balanced Dual-Mono Analog Output Stage

Each channel in the RD160 is assigned its own dedicated DAC module and operates through a fully balanced, symmetrical analog output stage. High-quality J-FET input dual op-amps, selected through a rigorous listening-based evaluation process and incorporating high-purity Oxygen-Free Copper lead frames, drive the balanced XLR outputs. The unbalanced RCA outputs utilize Ohno Continuous Casting (OCC) single-crystal copper cable in critical signal paths, ensuring signal transmission with minimal distortion and maximum purity. This dual-mono topology eliminates interchannel crosstalk and noise coupling, resulting in sharp, stable stereo imaging and an expansive, precisely layered soundstage.

Three Independent Reference Linear Power Supplies

The RD160 addresses power supply design with three completely independent, in-house-developed reference linear power supplies. One supply is dedicated to the digital input stage, while the remaining two independently power the left and right analog output stages. Ultra-low-noise chipsets form the core of each supply, and the physical separation of these power domains eliminates crosstalk and prevents digital switching noise from reaching the sensitive analog circuits. This independent power architecture directly enhances dynamic range, resolution, and soundstage depth while reducing power-supply-induced jitter.

Hidden AMOLED Display and Intuitive Interface

The RD160's front panel conceals a pair of polycarbonate AMOLED hidden screens (MIPI-DSI) that remain invisible when the unit is powered off, preserving the clean, uninterrupted lines of the solid aluminum chassis. Once active, the display presents a real-time flowchart of the signal path, showing the selected input, active digital filter, upsampling level, clock status, and output configuration. Six selectable digital filters, including minimum-phase and linear-phase options, as well as PCM-to-DSD upsampling up to 768 kHz, are navigable through front-panel controls or the included remote. The pre-out level is adjustable from 1V to 9V, and a variable output mode allows the RD160 to connect directly to a power amplifier without a separate preamplifier.

Frequently Asked Questions

What is the HiFi Rose RD160?

The HiFi Rose RD160 is a flagship standalone DAC from HiFi Rose of Seoul, South Korea, built around the AKM AK4499EX Velvet Sound Verita chipset, a dual-mono fully balanced ROSE CIM™ architecture, and an OCXO precision clock. It supports up to 32-bit/768kHz PCM and native DSD512, achieves a measured SNR of 124 dB, and is available in Canada through authorized HiFi Rose dealers including Vinyl Sound in Toronto.

How does the HiFi Rose RD160 compare to the Chord Hugo TT2 and PS Audio Stellar Gold DAC?

The HiFi Rose RD160 and Chord Hugo TT2 occupy similar price territory but take fundamentally different approaches to conversion. The Hugo TT2 uses Chord's proprietary FPGA-based Watts Transient Aligned filter and bespoke pulse array conversion, while the RD160 relies on the AKM AK4191EQ and AK4499EX chipset pair within a dual-mono isolated module architecture. Reviewers have noted the RD160 as highly forensic and spatially incisive, while the Hugo TT2 is broadly regarded as more holistic and tonally rounded. Against the PS Audio Stellar Gold DAC, the RD160 offers additional connectivity including AES/EBU input, a more elaborate chassis construction, and a more refined user interface, while the PS Audio competes closely on core sonic performance.

Can the HiFi Rose RD160 be used as a preamplifier?

Yes, the HiFi Rose RD160 can function as a preamplifier through its variable output mode. The pre-out level is adjustable from 1V to 9V, and selecting variable mode allows volume to be controlled directly via the front-panel knob or the included remote. This enables the RD160 to connect directly to a power amplifier without a separate preamplifier in the signal chain, simplifying the system and reducing the number of components between source and amplification.

What is the ROSE CIM™ architecture?

The ROSE CIM™ (Completely Isolated and Moduled) architecture is HiFi Rose's proprietary approach to separating digital and analog circuits within the RD160 onto physically distinct mono PCBs, one per channel. The AK4191EQ manages digital filtering and delta-sigma processing before handing off to the AK4499EX for final digital-to-analog conversion, with the two stages kept structurally separate to prevent digital noise from contaminating the analog output. This modular isolation delivers a measured SNR of 124 dB on coaxial and XLR outputs and eliminates the interchannel crosstalk that limits performance in conventional integrated DAC designs.

What is an OCXO clock and why does it matter in a DAC?

An OCXO, or Oven Controlled Crystal Oscillator, is the most thermally stable type of crystal oscillator available for audio applications. Conventional crystal oscillators are susceptible to frequency drift caused by temperature changes, which introduces jitter into the audio signal and degrades timing accuracy during digital-to-analog conversion. The OCXO in the HiFi Rose RD160 maintains a constant internal temperature, eliminating thermally induced oscillation fluctuations and producing a stable, ultra-precise clock signal that results in lower jitter across all digital inputs and a wider, more precisely focused soundstage.

Does the HiFi Rose RD160 work with the HiFi Rose RS130 network transport?

Yes, the HiFi Rose RD160 is designed to pair exceptionally well with the HiFi Rose RS130 network transport. The RS130 connects to the RD160 via USB or the fiber-optic USB SFP module, which provides galvanic isolation between the streaming and conversion stages for further noise reduction. Reviewers who have evaluated the RS130 and RD160 together consistently describe the combination as a cohesive reference-level digital front end within the HiFi Rose ecosystem.

What digital filter options does the HiFi Rose RD160 offer?

The HiFi Rose RD160 provides six selectable digital filters accessible through the front-panel controls, the included remote, or the AMOLED display interface. Available options include minimum-phase and linear-phase filter types, as well as PCM and DSD processing modes. Upsampling is available up to 768 kHz for 48 kHz-based content and 705.6 kHz for 44.1 kHz-based content, allowing listeners to tailor the sonic presentation to their preferences and system characteristics.
