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.
