Hi-Fi Rose RS451 Master Fidelity Network Streamer

Description RS451 At the heart of the RS451 lies the premium ES9027PRO DAC, configured with separate circuits for pre-out and headphone outputs to ensure dedicated, interference-free performance for each listening mode. The pre-out section integrates seamlessly into high-end systems, while the headphone DAC, supported by four powerful amplifiers, provides optimal impedance matching and clean, dynamic sound across a wide range of headphones. Combining these elements, RS451 sets a new benchmark in desktop streaming, offering refined audio precision without compromising space or versatility. Elegant & Functional Design The sleek aluminium chassis balances technical precision with visual refinement, making it a natural fit in diverse environments, from desktops to living room audio setups. Its compact proportions house an 8.8-inch high-resolution touchscreen (1920 × 480), designed to embody ROSE’s Visible Audio philosophy with vivid clarity and intuitive operation. The left side of the front panel hosts three headphone outputs—4.4mm balanced, 6.35 mm unbalanced, and XLR balanced—providing versatile connectivity for personal listening. On the right, a meticulously machined volume knob combines tactile satisfaction with minimalist aesthetics. The design is both durable and purposeful, with each detail engineered to enhance usability while showcasing HiFi Rose’s dedication to craftsmanship and user experience. Advanced Audio Technology Inside, the RS451 features a fully balanced, dual-DAC architecture with independent power supplies to minimize noise and maximize signal purity. The ES9027PRO DAC supports PCM up to 768 kHz and DSD512, with a dynamic range of 124dB and THD N of 114 dB, ensuring clean, high-resolution playback. The headphone amplifier employs four parallel-driven high-output ICs, delivering stable performance even with headphones above 600 Ω HiFi Rose’s proprietary ROSE DPC™ (Digital Processing Core) reduces jitter through I²S alignment, while the ROSE NRA™ (Noise Reduction Analog) filter ensures flat frequency response down to the lowest ranges. Powered by a next-generation 8-core CPU, the RS451 handles high-volume streaming, advanced processing, and ultra-low latency with precision and speed. Enhanced Connectivity & Features RS451 integrates the latest connectivity options to support modern Hi-Fi ecosystems. Its SIG-certified Bluetooth v5.4 module, powered by the Qualcomm QCC3083 chipset, delivers high-bitrate, 24-bit wireless audio with aptX support. Coaxial inputs now handle PCM 32-bit / 384 kHz and DSD128 formats, while HDMI eARC provides uncompressed 24-bit / 192 kHz audio transmission for true Hi-Fi integration. An upgraded IR remote control offers responsive, angle-free operation without pairing requirements. With an intelligently arranged rear panel, the RS451 ensures stable connections, reduced interference, and easy installation. Whether used as a core desktop setup or part of a larger audio system, the HiFi Rose RS451 Streamer combines high-end engineering, elegant design, and versatile features to deliver a truly immersive and uncompromising listening experience.
