ROSE HIFI RS451 Streamer DAC Headphone Amplifier Silver

With the RS451, ROSE HiFi presents a high-end streamer and headphone amplifier based on two ES9027PRO DAC chips supported by a vast array of technologies developed by the brand. The result is an AirPlay and DLNA-compatible device that has received Roon Ready and Play with Audirvāna certifications and is capable of processing signals up to PCM 32-bit 768kHz and DSD512 while delivering exceptionally clear sound reproduction.

Rose HiFi RS451: ROSE DPC digital treatment

The RS451 is equipped with the ROSE DPC (Digital Processing Core) module, which optimises digital signal processing. This module reduces jitter and improves signal quality by precisely synchronising input signals with a high-precision femto clock and aligning them as an I2S signal. Completely isolated from the device's other functions, this processing ensures natural, smooth sound that is compatible with a wide range of digital formats.

Rose HiFi RS451: ROSE NRA analogue processing

The analogue stage of the RS451 is equipped with the ROSE NRA (Noise Reduction Analog) filter, designed to eliminate noise and ensure a flat frequency response, even in extremely low frequency ranges. Thanks to this innovation, the RS451 ensures a fixed frequency response across the entire range without decay, faithfully and clearly reproducing the original sound information from high-resolution audio sources.

Rose HiFi RS451: 8.8-inch touchscreen

The RS451 features a generous 8.8-inch touchscreen with a resolution of 1920 x 480px, displaying album artwork and videos with incredible quality. The intuitive touch panel ensures exceptional ease of use, while its high resolution and wide colour gamut enable detailed and vivid visual representation.

Rose HiFi RS451: Extended compatibility

To become the nerve centre of your HiFi system, the RS451 is compatible with AirPlay and DLNA network protocols and allows you to connect to it via WiFi, Ethernet and Bluetooth. Furthermore, the RS451 is also compatible with a wide range of streaming applications such as Spotify, Apple Music, Tidal and Qobuz.

Rose HiFi RS451: Rose Audio Engine

The RoseAudioServer server solution developed by the brand integrates several signal processing technologies that work together to offer you the final result that is as faithful as possible to the original performance.

Audio Streamer Reader: The audio streamer reader utilises cache technology developed by HiFi ROSE to process digital input signals using system interrupts, network jitter and the base clock without distortion.

Audio Decoder: The audio decoder can process various types of audio sources and codecs to extract DSD and PCM data. In the case of a source using a lossy codec, it decodes to 32-bit floating point PCM to minimise distortion.

Audio Process: The audio process supports bit-perfect transmission, conditioning and delivering audio data in a transmission format optimised for the DAC used. It can support full MQA decoding and native DSD. It provides an advanced HiFi audio environment using various post-processing modules developed by HiFi ROSE.

Rose HiFi RS451: Rose Connect

With the Rose Connect app available on iOS and Android as well as MacOS and Windows, you can control the RS451 remotely so you can control your HiFi system from anywhere.
