Superior mono amplifier design with precise LC filter

The RA280 is equipped with two completely separate mono amplifier modules, each delivering 250W to both 4 ohm and 8 ohm speakers. In combination with HiFi Rose's advanced two-stage analog filter technology, it ensures a sound reproduction of the highest quality.

The special LC filter (inductance-capacitance filter) is designed to deliver a precise frequency response by reducing carrier noise from class-D amplifiers. With a -1 dB attenuation up to 65 kHz and -3 dB up to 85 kHz, the LC filter effectively filters out high-frequency noise signals, resulting in a clean and detailed sound. It improves spatial resolution and provides a much more analog sound than class-D amplifiers are normally capable of. This is one of the many reasons why the RA280 offers such a realistic and immersive listening experience as it does.

Impressively accurate RIAA amplifier for vinyl enthusiasts

For vinyl enthusiasts, the RA280 offers a precision RIAA amplifier optimized for moving magnet pickups. This amplifies the delicate sound signals of the pickup with impressive accuracy and without distortion. HiFi Rose's precision compensation circuit ensures that the sound stays true to the original recording, providing a rich and dynamic sound that brings your vinyl records to life.

Advanced power supply for optimal performance

The RA280 is equipped with a cutting-edge power supply that uses silicon carbide FETs for high efficiency and low heat generation. This innovative design ensures optimal power delivery and stability, even during rapid load changes. With a 2.5 power factor correction circuit and a high-capacity capacitor, the RA280 delivers consistently high performance, ensuring deep bass and precise treble tones. The fourth generation of Silicon Carbide (SiC) FET technology improves current delivery and reduces heat, resulting in powerful and accurate sound reproduction.

Impressive build quality and retro design with VU meters

The HiFi Rose RA280 combines modern technology with a timeless, retro design. The robust aluminum cabinet not only provides an impressive build quality, but also reduces unwanted vibrations that can degrade sound quality. The stylish retro design includes classic VU meters that not only add visual appeal, but also provide an intuitive display of sound levels. This design choice brings a nostalgic feel back to your listening experience while delivering the highest quality of modern audio technology.

Uncompromising input options for ultimate sound quality

The HiFi Rose RA280 is designed with uncompromising sound quality in mind, which is why it only offers analogue inputs. This deliberate design choice ensures that the analog signal is processed without interference from digital input circuitry. HiFi Rose has chosen to separate the digital inputs and place them in their streamers, which act as central hubs for all digital processing. This separation optimizes the analog signal path and ensures an unrivaled sound quality. The RA280 is equipped with both balanced XLR outputs and unbalanced RCA outputs, providing maximum flexibility and quality in your sound setup.
