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 separation of digital and analog signal paths. Three independent custom linear power supplies, a high-precision OCXO clock, and ROSE NRA™ and ROSE DPC™ processing modules combine to deliver a level of engineering refinement rarely seen outside of reference-class digital components. The result is a DAC that brings extraordinary resolution, low noise, and spatial accuracy to any high-end two-channel system.

ROSE DPC™ Digital Processing Core: Precision From the Ground Up

The ROSE DPC™ (Digital Processing Core) module forms the foundation of the RD160's digital architecture. All digital processing blocks within the module are engineered to maintain optimal signal accuracy, synchronizing incoming digital signals from any connected source to a high-precision OCXO clock and aligning them as I2S signals before conversion. This synchronization and clock-locking process is especially critical when handling high-resolution audio formats, where even minute jitter artifacts can degrade transient clarity and tonal purity. Crucially, the 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 the standard approach to DAC design and pushes it significantly further. In the RD160, 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 for each channel. This structural isolation achieves an extremely high signal-to-noise ratio, effectively eliminating the cross-contamination between digital switching noise and sensitive analog signals that limits performance in conventional single-board DAC designs. The measured SNR of 124 dB on both coaxial and XLR outputs is a direct result of this modular approach.

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 effectively eliminates interchannel crosstalk and noise coupling, resulting in sharp, stable stereo imaging and an expansive, precisely layered soundstage.

Three Independent Reference Linear Power Supplies

Power supply design is one of the most consequential factors in DAC performance, and the RD160 addresses it 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 respectively. 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 the reduction of power-supply-induced jitter contributes to the RD160's wide, precisely focused spatial presentation.

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 in a visually engaging horizontal layout. Six selectable digital filters, including minimum-phase and linear-phase options, as well as PCM-to-DSD upsampling up to 768kHz, are all navigable through the front-panel controls or the fully featured 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, eliminating the need for a separate preamplifier.

Frequently Asked Questions

What is the HiFi Rose RD160?

The HiFi Rose RD160 is a flagship standalone digital-to-analog converter from HiFi Rose, a specialist audio brand developed by South Korean technology company Citech. It is built around the AKM AK4499EX Velvet Sound Verita DAC chip, operates with a dual-mono fully balanced architecture, and supports up to 32-bit/768kHz PCM and native DSD512. The RD160 is HiFi Rose's first dedicated DAC and is engineered as a reference-level source component for serious two-channel audio systems.

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

The HiFi Rose RD160 and the Chord Hugo TT2 occupy similar price territory but take fundamentally different approaches to digital-to-analog 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 incisive with strong spatial characteristics, 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 higher-grade chassis, and a more elaborate user interface, while the PS Audio competes closely on core sonic performance at a lower price point.

Can the HiFi Rose RD160 be used as a preamplifier?

Yes, the 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 the 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 requiring 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 the digital and analog circuits within the RD160 onto physically distinct mono PCBs, one per channel. The AK4191EQ manages digital filtering and delta-sigma processing, then hands off to the AK4499EX for the actual digital-to-analog conversion, with the two stages kept structurally separate to prevent digital noise from contaminating the analog output. This modular isolation delivers an ultra-high signal-to-noise ratio of 124 dB on coaxial and XLR outputs and eliminates the interchannel crosstalk that limits performance in conventional integrated DAC PCB designs.

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

An OCXO, or Oven Controlled Crystal Oscillator, is the most accurate and 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 RD160 maintains a constant internal temperature, eliminating thermally induced oscillation fluctuations and producing a stable, ultra-precise clock signal. The result is lower jitter across all digital inputs, more accurate signal reconstruction, and a wider, more precisely focused soundstage.
