Product Description
The HiFi Rose RS451 is positioned as a premium network streamer/DAC/preamp that excels in providing an exceptional, flexible, and feature-rich digital audio experience, with a particular focus on a reference-grade headphone listening stage.
Dual DAC Architecture: It features two ESS SABRE ES9027PRO DAC chips—one is dedicated to the pre-out (line-level analog outputs), and the other is exclusively for the headphone output. This separation and the use of a 4-channel parallel structure for stereo output aim for ultra-low noise and high dynamic range.
High-Resolution Audio: It supports playback of incredibly high-resolution formats, including PCM up to 32-bit/768 kHz and Native DSD512.
Precision Clocking: It incorporates a Highly precise Femto Clock to minimize jitter and ensure accurate timing for a clear, natural sound.
Noise Reduction: It utilizes the proprietary ROSE NRA (Noise Reduction Analog)™ Filter in the analog stage to eliminate noise and maintain a flat frequency response across the entire spectrum.
Toroidal Linear Power Supply: The use of a toroidal linear power supply and independent power delivery per channel helps create a stable, low-noise foundation for the audio.
The dedicated headphone DAC is paired with a powerful amplifier section featuring four individually driven amplifier ICs.
