HiFi Rose RA280 – 2 x 250 W Integrated amplifier with advanced Class-AD technology and outstanding sound quality

HiFi Rose RA280 is designed for audiophiles who demand the very best. With advanced Class-AD technology and next-generation GaN (gallium nitride) FETs, the RA280 delivers sound quality that rivals the finest analog amplifiers while maintaining outstanding efficiency and power. This innovative amplifier technology ensures an almost perfectly linear output with minimal distortion, resulting in natural sound reproduction. From the deepest bass tones to the finest high-frequency details, the RA280 covers a wide frequency range from 20 Hz to 100 kHz and creates an immersive and realistic listening experience.

• A more natural, energetic, and analog sound than conventional Class-D amplifiers
• Advanced Class-AD amplifier with GaN FETs for precise sound without distortion
• 2 x 250 watts into 8 and 4 ohms
  
• Balanced inputs and superb RIAA amplifier
• Treble and bass adjustment
• Tone control with bypass switch
• Illuminated analog VU meters (3 lighting levels)
• Analog stereo RCA phono input for moving magnet cartridges
• 3 x line-level analog stereo RCA inputs
• Mono RCA output for connecting an active subwoofer
  

Superior mono amplifier design with precise LC filter

The RA280 is equipped with two completely separate mono amplifier modules, each delivering 250 W to both 4-ohm and 8-ohm speakers. Combined with HiFi Rose’s advanced two-stage analog filter technology, this ensures sound reproduction of the very 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 -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 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 captivating listening experience. 

Impressively precise RIAA amplifier for vinyl enthusiasts

For vinyl enthusiasts, the RA280 offers a precision RIAA amplifier optimized for moving magnet cartridges. This amplifier handles the cartridge’s delicate audio signals with impressive accuracy and without distortion. HiFi Rose’s precision compensation circuitry ensures that the sound remains true to the original recording, delivering a rich and dynamic sound that brings your vinyl records to life.

Advanced power supply for optimal performance

The RA280 is equipped with a groundbreaking 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 consistently delivers high performance, ensuring deep bass and precise treble tones. The fourth generation of Silicon Carbide (SiC) FET technology improves power delivery and reduces heat, resulting in powerful and accurate sound reproduction.

Impressive build quality and retro design with VU meters

HiFi Rose RA280 combines modern technology with a timeless retro design. The robust aluminum chassis not only provides 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 the 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

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