Stunning Streaming Integrated Amp with Flagship DAC and 12.6"-Wide Hi-Res Touchscreen
HiFi Rose's RS520 is the perfect centerpiece for hi-res music listening, incorporating a built-in network player, DAC, and powerful, 250 watt per channel integrated amplifier. It's a do-it-all product that consolidates the main functions of existing all-in-one streamers into a premium component based on ROSE’s unique design expertise accumulated over many years.
For its DAC module, the RS520 is equipped with ES9038PRO DAC, the flagship DAC chip of ESS technology. The amp section is just as impressive, relying on HiFi Rose's innovative GaNFET amplifier.
If you're looking to upgrade your amp and streamer, the RS520 is the perfect purchase. You'll get top quality performance and end up saving enough money to treat yourself to a better pair of speakers, too.
"Recommended Component" Honors
Stereophile honored the RA 180 by awarding it the magazine's coveted Recommend Component status for 2024.
According to Stereophile, "It offers a plethora of audio and video streaming functionality, as well as offering optical and coaxial S/PDIF inputs, USB ports for attaching local storage, and WiFi and Bluetooth connectivity. RvB controlled the RS520 with the HiFi Rose smartphone app and with all the speakers with this he used the amplifier found that there was weight, control, authority, clarity, and palpability. 'I heard sweet detail up top that didn't become brittle even on borderline sibilant recordings,' he wrote, concluding that the HiFi Rose is 'a fast, impressively appointed sports car for the price of a Volkswagen Golf. Fahrvergnügen indeed!'"
"Fast… Delectable," Raves Stereophile
The RS520 was featured on the cover of the July 2023 issue of Stereophile magazine. According to reviewer Rogier Van Bakel, "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.'"
Van Bakel sums up: "The HiFi Rose is a fast, impressively appointed sports car for the price of a Volkswagen Golf."
"Utterly Captivating"
Hi-Fi Choice magazine's Ed Selley listened to a piece of music on the RS520 and calls it "a head-nodding, grin-inducing, utterly captivating experience." Selley goes on to say, "It’s worth celebrating that setting it up is an object lesson in how to make the process user-friendly. It displays clear prompts as to what it’s up to, lays menus out in a way that generally makes sense and demonstrates unconditional stability."
New-Concept Class AD Amplifier
A power output of 250 watts-per-channel with Hi-Fi Rose's breakthrough GaNFET amplifier maximizes operating speed and accuracy to achieve stunning, powerful amplifier performance in a compact chassis.
Class AB amplifiers were developed to improve the high heat generation and low efficiency of Class A. Class D has higher efficiency and higher output than AB, with significantly improved S/N and THD characteristics compared to Class A and Class AB. However, in the past the sound quality has often been regarded as inferior to Class A/AB due to the limitations of the digital circuit.
The GaNFET amplifier developed by HiFi Rose has dramatically improved the performance vs. the existing silicon-FET based Class D amp design by applying innovative new materials and technology. These Gallium Nitride FETs switch on and off at faster speeds than the MOSFETs, resulting in what HiFi Rose calls a "high-speed, perfectly accurate amplification stage" with an analog sound quality.
Flagship ES9038PRO DAC
The RS520 is equipped with the SABRE ES9038PRO, the flagship DAC chip of ESS technology. This AC module is one of the highest performance 32-bit solutions on the market today designed for audiophile and studio equipment applications.
Using the critically acclaimed ESS’ patented HyperStream® II architecture and Time Domain Jitter Eliminator, the ES9038PRO delivers an unprecedented dynamic range (DNR) of up to 140dB and THD+N of –122dB, the industry’s highest performance level that will satisfy the needs of the most demanding audio applications. The maximum sampling frequency and bit rate are PCM 768 kHz, 32 bit, and DSD512 is supported.
The ES9038PRO significantly reduces software implementation time compared to previous products, and it minimizes gain error between devices by automatically adjusting gain. In addition, it is equipped with ESS technology's exclusive jitter canceller to provide exceptional audio clarity. Seven low-delay filters allow you to sculpt your music to meet your tastes and suit your ears.
Solid Aluminum Casework
The casework of the RS520 is made with generous use of high-durability 6000 class aluminum, manufactured by an all-in-one process from a single chunk of aluminum, in which four sides are produced as one part. The resulting housing blocks vibrations that may occur between separated parts, significantly reducing vibration that could otherwise affect sound quality.
12.6"-Wide Touch Screen and ROSE Connect
Advanced control of the RS520 is provided by the integrated 12.6"-wide touch screen. It provides an intuitive and convenient interface through the high-resolution wide viewing angle and IPS multi-touch functionality. The front display shows high-definition album information and can also play back video at 60 FPS.
Additionally the dedicated Rose Connect Application allows you to play all music and videos from local and network sources. It is available for Apple and Android devices through Apple and Google Play stores. Yet another control option is provided by the included Bluetooth remote, which lets you interface with the RS520 with ease.
MQA Certified with Built-in TIDAL
The RS520 supports MQA full decoder technology. MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. A built-in TIDAL App is integrated for high-performance streaming.
