The RS451 is the most versatile streamer HiFi Rose makes. It sits in the middle of the streamer line, between the RS250A and the reference RS151, and it is the first Rose streamer to combine a balanced XLR pre-out with a genuine high-power headphone amplifier — so it works as the front end of a two-channel system and as a serious desktop headphone setup, with no compromise to either. Stream from the main listening chair, then listen privately at the desk, all from a single component.

Two Components in One

Most streamers ask you to choose between a line output for your system and a headphone jack as an afterthought. The RS451 refuses the trade-off. It carries two independent ESS SABRE ES9027PRO DACs — one assigned to the pre-out, one to the headphone output — each with its own dedicated power supply and its own grounding. The signal feeding your amplifier and the signal feeding your headphones never share a path, so neither stage is held back by the other.

A Headphone Amplifier Built to Drive Anything

The RS451's headphone stage uses four parallel high-output amplifier ICs to deliver real current. It drives demanding headphones — loads beyond 600 ohms — with stability and ultra-low distortion, which means it stays composed with the kind of high-impedance designs that defeat the headphone jacks built into most streaming hardware. This is a headphone amplifier you would be glad to own on its own.

The Screen That Runs Everything

An 8.8-inch IPS capacitive touchscreen puts the full ROSE OS interface under your fingertips — album art, your library, every streaming service, and HiFi Rose's custom VU meters. The RS451 is a component you operate directly, not a black box you control from across the room with a phone. When you would rather use a phone, the ROSE Connect app is there.

The Best Streaming, Built In

The RS451 is Roon Ready and streams natively from Tidal, Qobuz, Apple Music, and Spotify Connect, with AirPlay 2, Bluetooth 5.4 aptX, and DLNA covering everything else. Whatever your music library lives in, the RS451 plays it — controlled from the touchscreen or from the ROSE Connect app on iPhone, iPad, Android, or PC.

Engineered for a Quiet Signal

HiFi Rose's ROSE NRA — Noise Reduction Analog — filter works to keep the analog signal path clean, so what reaches your amplifier and your headphones is the music and not the noise around it. It is part of why the RS451 sounds as composed as it does across both of its outputs.

Fast Inside, Generous Outside

A next-generation 8-core RK3588 processor with 8 GB of RAM and 32 GB of onboard storage keeps ROSE OS quick and responsive, even with a large library and a busy interface. Connectivity is comprehensive: balanced XLR and unbalanced RCA pre-outs, optical and coaxial digital outputs, a USB 3.0 Type-A output, an HDMI eARC input for your television, a 4K HDMI 2.0 output for video, plus line, optical, coaxial, and USB inputs.
