Its class leading specifications enabling delicate and clean sound reproduction. Supporting PCM up to 768kHz and DSD512, it ensures perfect compatibility with high-resolution audio formats. The variety of digital filters also offer a degree of sound customisation, to suit different styles of music or listening preferences.\u003c\/span\u003e \u003c\/p\u003e\n\u003ch2\u003eAdvanced Headphone Architecture\u003c\/h2\u003e\n\u003cp\u003e\u003cspan class=\"NormalTextRun SCXW110671563 BCX0\"\u003eBy utilising two DAC chips within its advanced circuitry, the RS451 can deploy one chip for the traditional pre-out stage, and a separate one for the headphone output stage. In this way, the two signal paths are completely separated. The high-performance headphone stage further consists of four individually driven amplifiers that provide strong and stable output, even for low-impedance headphones. Further clarity and performance are guaranteed by the isolated power supply design for each channel. The result is a truly first-class headphone system, all in one box.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eInnovative Signal Processing\u003c\/h2\u003e\n\u003cp\u003e\u003cspan class=\"NormalTextRun SCXW246923937 BCX0\"\u003eThe RS451 makes use of Rose’s Digital Processing Core (DPC) Module, which was originally developed for the RD160 DAC and further employed in the RS151. This module precisely synchronizes any digital signal the DAC receives with a high-precision Femto clock as an I2S signal. It applies clock synchronization and locking processes to minimise jitter, allowing for accurate processing and a natural, clear sound performance. By isolating this module away from the wider CPU circuitry, it’s possible to eliminate signal distortion and interference that’s generated within the unit from the digital audio path. The result is accurately processed data, resulting in a natural and clean sound across a wide range of digital formats. \u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eROSE OS\u003c\/h2\u003e\n\u003cp\u003e\u003cspan class=\"NormalTextRun SCXW45423682 BCX0\"\u003eAt the centre of the RS451 is ROSE OS, HiFi Rose’s Android-based operating system, which opens a world of music and video content to your streamer. ROSE OS supports local network music playback within Rose’s Music app, as well as CD playback and ripping via a connected optical drive. There is also support for internet radio, Spotify Connect, Tidal, Qobuz and Apple Music. The RS151 is also Roon Ready and Plays with Audirvāna certified. In addition, the operating system offers support for video playback, either locally or within the Tidal or Rose Tube apps. \u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eConnect what you need\u003c\/h2\u003e\n\u003cdiv class=\"OutlineElement Ltr SCXW132837165 BCX0\"\u003e\n\u003cp class=\"Paragraph SCXW132837165 BCX0\"\u003e\u003cspan class=\"NormalTextRun SCXW132837165 BCX0\" data-ccp-parastyle=\"Normal (Web)\"\u003eThe RS451 offers a well-organized rear panel layout with intuitive port placement, tailored for real usage scenarios.
