RA280
The RA280 is a feature rich integrated amplifier, designed to deliver a pure, natural sound that puts the musical experience first. The elegant exterior design complements any listening space thanks to its two finish options, but hidden within is a powerhouse amplifier that uses the latest HiFi Rose technologies.

Sound Design 

The overall design of the RA280 matches that of HiFi Rose’s full-width streaming products. However, its elegant industrial aesthetic can complement any modern listening space. The sturdy aluminium chassis gives a reassuring weight and solidity to the build, while also doing a good job of isolating surrounding interferences from the sensitive electronic circuitry inside. The top-mounted vents bring further character to the design, while also allowing for heat dissipation from within.  

A New Standard in Amplifier Design 

The RA280 is based around HiFi Rose’s Class AD Amplifier technology. Class D amplification provides higher efficiency and higher output, as well as improved noise and distortion measurements, compared to more traditional Class AB designs. However, many Class D designs in the past have suffered in sound quality due to limitations in their circuitry. HiFi Rose’s state-of-the-art Class AD (“Advanced D”) amplifier resolves these problems with the use of innovative new materials. 

The RA280’s Class AD amplifier boasts Gallium Nitride FETs as opposed to more common Silicon FET technology. The result of this design is a high-speed, perfectly accurate amplification stage with almost no dead time, allowing it to perform far more naturally, like a pure analogue amplifier.  

All That Power 

The RA280 boasts separate 250W (4Ω and 8Ω) amplifier modules per-channel, delivering 500W of total system power. The power stage also makes use of a HiFi Rose-designed two-stage analogue filter to achieve the best sound quality. The LC filter helps support the amplifier’s excellent frequency response by offering -1dB attenuation in the frequency band up to 65kHz and -3dB attenuation in the 85kHz range. This technology dramatically reduces carrier noise caused by the inherent switching of Class D amplifiers, providing clearer and cleaner sound quality throughout the frequency range. This further supports the RA280’s analogue sound signature. 

Customisable Experience 

The RA280’s front panel offers access to Bass and Treble tone controls, allowing users to adjust the flat frequency response at 100Hz and 10kHz, respectively, with ±15dB gain for a fully tailored sound. Elsewhere the built-in MM phono stage has been purpose-designed to deliver distortion-free pre-amplification for a connected turntable.  

Quality Throughout 

The RA280 features one balanced and three unbalanced inputs alongside the built-in phono stage. There is also support for a subwoofer output, trigger connections and a grounding post alongside the speaker output terminals. But the wide array of features, technologies and connectivity options are all able to perform optimally thanks to the new power supply design. 

The power supply was first developed for the flagship RA180 amplifier. It employs Silicon Carbide FET technology, with its high voltage support and heat resistance, to provide a high output in an efficient manner with low heat generation. It also responds to power delivery fluctuations well with its 2.5kW class PFC circuit and high-capacity condenser. The result is a power supply that responds to the needs of the system, while always allowing the amplifier to sound as clean and natural as possible.  

A True Master 

The RA280 is a feature-rich, yet intuitive integrated amplifier that delivers in every way – whether you are driven by engineering, aesthetics, or pure, unrivalled sound quality. Try it out today.

HiFi Rose BEST Amplifier: NEW RA280 vs EXQUISITE RA180

"Both amplifiers are using the new GaN FET HiFi Amplifier technology which I was keen to listen as its said to a better class D and I was very impressed here. I could not tell, especially with the RA280 that I was listening to a variant of class D. Both amplifiers sound very fast with great bass and detail and dynamics. "

David Price , StereoNet Applause , November 2024

David Price is beguiled by this fragrant-looking, potent-sounding integrated from South Korea…

"The RA280 might look retro, but doesn't sound it. This is a highly enjoyable amplifier which goes against the grain of some people's preconceived ideas about Class D-type sonics."

The RA series are amplifiers from start to finish, and what an amp they are! The immediate impression is of the 'Timelord-esc' design of the front panel, with multiple moving knobs and dials that are just oh-so-satisfying to operate. 

But once you're done playing with the interface you get the chance to experience something technologically impressive too! Two amplifier modules per channel allow for bi-amping in one box, and the result is a clean, stable performance that is sure to impress.
