HiFi Rose

The precise design and innovative technologies of HiFi ROSE, all concentrated on our product RD160, will guide you into a world of purer and more genuine sound. The RD160 offers a digital processing core module that precisely processes digital signals, an architecture to separate digital and analog signals and convert them transparently and precisely without distortion, a fully balanced design to maintain the highest signal purity, three power supply units to independently supply power to each circuit for clearer and more dynamic sound, and even a noise filter to vividly convey the finest details of the sound. ROSE DPC(Digital Processing Core)™ ModuleThe digital stage of the RD160 is equipped with the ROSE DPC™ module, where all processing blocks are designed to maintain optimal signal accuracy and precision, ensuring the delivery of high-fidelity sound.This module precisely synchronizes digital signals input from various methods to a high-precision OCXO clock, aligning them as I2S signals. Especially when processing high-resolution audio signals, the module applies clock synchronization and locking processes to minimize jitter, resulting in accurate signal processing and natural, clean sound. 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 RD160 guarantees superior digital signal quality and ensures high-quality sound with compatibilityacross various digital formats.Three Customized Reference Linear Power UnitsThe reference linear power supplies in the RD160, developed in-house by ROSE, are engineered to achieve the highest sound quality using ULTRA LOW NOISE power chipsets. These power supplies independently feed the digital input stage and the left and right analog output stages, minimizing crosstalk and interference between sections. This design effectively suppresses noise across the digital processing, clock, and analog output circuits, ensuring signal integrity.By delivering stable power tailored to the specific needs of each stage, it enhances the DAC’s dynamic range and resolution, faithfully conveying even the most subtle details of the music. Additionally, the reduction of jitter maximizes the spatial characteristics of the soundstage, resulting in a wider and more precise soundstage with sharp imaging. Through this power supply design, the RD160 elevates audio clarity and dynamics, offering a deeply immersive listening experience.

The RS520 is packing the main functions of existing all-in-one streamers into a single component with a powerful output of 200 watts per channel. The RS520's chassis is milled from a solid highly-durable aluminum block. This process creates an extremely rigid frame that significantly reduces noise-generating micro-vibrations that can degrade sound quality.

With a focus on delivering pristine sound, the RS130 is engineered to eliminate digital noise and ensure stable output. Its support for Fiber Optic Ethernet and Fiber Optic USB effectively blocks unwanted noise sources, allowing you to indulge in pure audio bliss. The built-in high-precision OCXO clock guarantees precise timing, maintaining a constant temperature for stable and accurate clock signals.

The RA280 is an integrated amplifier that inherits the innovative technologies used in RA180. Enjoy pure natural sound as close to the original sound as you can get with the RA280: a near-perfect sound that transcends the boundaries between digital and analog technologies with excellent linearity achieved through strong power damping and short dead time. The RA280 offers a special listening experience that lets you feel the true essence of music.
