Advanced All-In-One Network Streamer

Rose RS520

RS520 is an all-in-one product with built-in network player, DAC, and amplifier. For DAC and amplifier module, it is equipped with ES9038PRO DAC, the flagship DAC chip of ESS technology and Class AD amplifier module developed by applying new material GaN FET are mounted. RS520 is an advanced all-in-one network streamer that consolidates the main functions of existing all-in-one streamers into one based on ROSE's unique design know-how and functions accumulated over many years.

Combination of Convenience and Top-Notch Sound Quality: The Birth of a New All-in-One Network Streamer

Unchangeable Value

The design of the RS520 focused on values that did not change over time. A refined design that will not change over time and a bold ventilation hole for heat dissipation represent a gentleman with both functionality and enterprising appearance.

Integral Aluminium Housing

The housing of RS520, which is made with generous use of high-durability 6000 class aluminum material, is manufactured by an all-in-one process in which four sides are produced as one part. The all-in-one manufacturing process is the most ideal method to fundamentally block vibrations that may occur between separated parts, significantly reducing noise waves that can affect sound quality.

12.6-Inch Wide LCD Touchscreen

Visible audio is emphasized using HiFi ROSE's spacious, wide-viewing-angle multi-touch LCD screen. With a size of 309*82.9 (mm) and a 1920*515 resolution LCD panel, you can enjoy a smooth and clear screen.

High-Resolution Audio

HiFi ROSE is officially certified as "High-Resolution Audio" licensed by the JAS (Japan Audio Society).

ES9038PRO DAC

It is equipped with ES9038PRO, the flagship DAC chip of ESS technology, a world-class DAC manufacturer. ES9038PRO has extremely low total harmonic distortion plus noise (THD+N) of-122 dB, and dynamic range (DNR) of 140 dB, making it the industry's best DAC chip. The maximum sampling frequency and bit rate are PCM 768 kHz, 32 bit, and DSD512 is supported. In addition, it is equipped with ESS technology's exclusive jitter canceller to provide exceptional audio clarity.

Discrete OP AMP

Discrete operational amplifier developed by ROSE is applied to the IV circuit that is essential for current DAC. HIFI ROSE focused on high open loop gain and aimed to achieve low open loop distortion, low noise, low drift, and low off set, In addition, this operational amplifier has a wide bandwidth and power supply range essential for high-quality analog audio amplification, adding a sense of depth to the sound. So, by reproducing the vividness of the deep bass and treble like a live performance, it makes the resonance of the inter- band connection very comfortable.

ACTIVE PFC

The main reason for applying power factor correction (PFC) is efficiency improvement. ※Active PFC efficiency: 95% / Passive PFC efficiency: 68-80% By adopting Active PFC technique, the highest power saving effect with 95% efficiency can be expected. In addition, it can respond more effectively to a wide range of input power of AC 80-265 V, so the power quality can be improved and it does not produce audible audio hum noise.

GaN based Class AD Amplifier

The class-AD amplifier mounted on RS520 uses a new material GaN (gallium nitride) FET to dramatically reduce the "dead time" by 1/3 to maximize linearity. Please enjoy the powerful output of 250 W per channel with HiFi ROSE's class-AD amplifier that maximizes operating speed and accuracy to achieve the perfect class-D amplifier structure.

Equalizer

RS520 supports the equalizer function (hereafter EQ) that can emphasize (boost) or attenuate a specific frequency band of a voice signal. The RS520 EQ is a parametric equalizer that can set the frequency band for amplification and attenuation arbitrarily, and can adjust the bandwidth of the Q-factor for each frequency. Five frequency bands can be set, and each can be adjusted up to ±10 dB.

Connect anything

You can enjoy seamless streaming through the network. It supports Airplay and DLNA functions. Also, you can connect the device to a smartphone, computer, or tablet PC through WiFi/Giga Ethernet / Bluetooth communications.

ROSE Connect Application

It includes a Dedicated Remote Control Application that allows users to conveniently control and smartly manage ROSE devices. The remote control application works on various platforms including iPhone, iPad. Android phone, and PC.

Innovative ROSE OS system

HiFi ROSE's own OS system provides an innovative listening environment. In addition to playing and streaming ultra-high-quality music, it offers a variety of services including 4K high-definition video playback, music-oriented YouTube listening, Pod casts, various radio broadcasts around the world, CD playback and ripping.

Rose Audio Engine

HiFi ROSE can deliver pure audio data to DAC without loss by using RoseAudioServer, developed by ROSE, and realizes advanced high fidelity audio service by using various signal processing technologies.

REVIEW & AWARDS

"Having delivered fine-sounding network players and an amplifier, HiFi Rose brings it all together in this highly accomplished all-in-one unit. There's plenty to play with, or you can just connect your favourite speakers and get on with enjoying the music. Highly flexible, and packed with features you'll use – plus some you probably won't – this a superb contender in what is a fast-growing sector of the market." - Andrew Everard

"I loved my time with the RS520; this Rose is blessedly free of thorns. It's a serious piece of cutting-edge technology, uniquely outfitted with a user interface that's infused with playfulness. The Rose is free of glare, grain, and tizziness, unlike most class-D amplifiers of 10–12 years ago. Audiophiles of a certain vintage tend to swear by class-A or class-AB amps, but their knees may be jerking. D may have once stood for "Don't"; now, perhaps we can settle on "Delectable."" - Rogier van Bakel

Review HiFi Rose RS520: evolution - Read More

"It won't be long before HiFi Rose is a real household name in the market. With the design of the RS520, the manufacturer has managed to put a product on the market that is accessible to everyone. A scalable hifi concept that responds to the needs of all new media forms, but also respects the traditional way. If the user experience continues to grow and develop, we will reward that with the full five stars." - Quintijn Bulterman

HiFi ROSE RS520 - Read More

"The complete and yet compact HiFi audio system ROSE RS520 is probably the ideal manifestation of the company's philosophy - it is small, nicely made, quite easy to use and combines solid connectivity (if you need something extra, although the target group is mainly those who do not need anything else) with a very pleasant, even elegant sound performance that can tirelessly accompany you for long hours. The RS520 may not raise your heart rate to your physiological maximum, but you can let yourself be pampered and bathed in music, play whatever comes to mind easily and comfortably, and from a technical point of view you will get it in quality and control that corresponds to a system approaching the hundred thousand mark. It is a truly nice all-in-one..." - Daniel Březina

HiFi Rose RS520 Streaming Amplifier Review - Read More

"It has been a while since I reviewed a fun product. The RS520 is not only a solidly built audio component, but a versatile music player that is designed to be easy to use, customizable, and full of fun-to-explore features. If I were looking for a single component to showcase my full range speakers, the RS520 checked off almost all the boxes I have… and some boxes I didn’t know I had! All other amplifier streamers I review in the future will be measured against the benchmark of the HiFi Rose RS520." - Jim Milton
