RA280 Integrated Amplifier

Product Description

The HiFi Rose RA280 Integrated Amplifier exemplifies the seamless blend of advanced technology and elegant design, crafted to deliver an unparalleled audio experience. Building on the legacy of its predecessor, the RA180, this new model integrates the revolutionary Advanced Class D amplification technology to offer both high efficiency and superior sound quality.

Innovative Advanced Class D Technology
HiFi Rose redefines digital amplification with the RA280’s Advanced Class D technology, featuring next-generation GaN (gallium nitride) FETs. This breakthrough innovation surpasses traditional Class D amplifiers, delivering sound quality comparable to analog while maintaining superior efficiency and power. The RA280 achieves near-perfect linear output with minimal distortion, ensuring smooth, natural sound reproduction. Covering a wide frequency range from 20 Hz to 100 kHz, the RA280 faithfully renders every audio detail, creating a truly immersive and realistic listening experience.

Superior Mono Amplifier Design with Advanced Filtering
The RA280 stands out with its two completely separated mono amplifier modules, each delivering 250 W (4 Ω and 8 Ω) to the left and right channels, for a total of 500 W in stereo mode. HiFi Rose’s advanced two-stage analog filter technology ensures top-tier sound quality. The LC filter provides exceptional frequency response, with -1 dB attenuation up to 65 kHz and -3 dB up to 85 kHz, effectively reducing carrier noise from Class D amplifiers. This results in pristine, detailed sound, enhanced spatial resolution, and a natural analog feel.

Precision Phono Amplifier for Moving Magnet Cartridges
Elevate your vinyl listening experience with the RA280’s precision phono amplifier, designed for moving magnet cartridges. This high-performance amplifier, activated via a simple switch, amplifies delicate audio signals without distortion. HiFi Rose’s high-precision compensation circuitry delivers sound that is remarkably close to the original recording. This ensures rich, vivid detail and superior sound quality, providing an immersive and high-fidelity music playback experience that brings your records to life.
 
Cutting-Edge Power Supply for Unmatched Performance
HiFi Rose’s RA280 features a state-of-the-art power supply, utilizing silicon carbide FETs for superior efficiency and reduced heat compared to traditional silicon FETs. This innovative design ensures optimal power delivery and stability. The inclusion of a 2.5 power factor correction circuit and a high-capacity condenser maintains excellent performance even under rapid load changes, ensuring consistent and high-quality sound. The fourth-generation Silicon Carbide (SiC) FET technology enhances power output while minimizing heat, supporting deep bass and precise treble tones for powerful and accurate audio reproduction.
