The RA280 sports activities a feature-rich design and cutting-edge HiFi Rose applied sciences, promising a pure, pure sound that can depart you breathless.
The HiFi Rose RA280 boasts an exterior design that enhances any trendy listening house and is extra minimalist than the putting RA180. Its sturdy aluminium chassis ensures a stable construct that may face up to the check of time whereas defending the delicate digital circuitry inside from surrounding interference. The highest-mounted vents add character to the design whereas permitting for warmth dissipation from inside.
On the coronary heart of the RA280 is HiFi Rose’s Class AD Amplifier know-how (Superior D), which supplies larger effectivity, larger output, and improved noise and distortion measurements than conventional Class AB designs. Not like many Class D designs prior to now, the corporate states that RA280’s state-of-the-art Class AD amplifier makes use of revolutionary new supplies to ship a high-speed, completely correct amplification stage with nearly no lifeless time, permitting it to carry out way more naturally, “like a pure analogue amplifier.”
With separate 250W (4Ω and 8Ω) amplifier modules per channel, the RA280 delivers a complete system energy of 500W, making it a real powerhouse. The LC filter helps assist the amplifier’s glorious claimed 10 Hz – 66 kHz (-1 dB) frequency response by providing -1dB attenuation within the frequency band as much as 65kHz and -3dB attenuation within the 85kHz vary.
We’re advised this dramatically reduces provider noise attributable to Class D amplifiers’ inherent switching and supplies extra exact and cleaner sound high quality (S/N Balanced/ Unbalanced: 109dB) all through the frequency vary.
The RA280 additionally boasts a wide range of connectivity choices, together with one balanced and three unbalanced inputs alongside the built-in MM phono stage.
In the meantime, the entrance panel presents Bass and Treble tone controls, permitting you to regulate the flat frequency response at 100Hz and 10kHz, respectively, with ±15dB achieve for a totally tailor-made sound. Alongside the speaker output terminals, there may be assist for subwoofer output, set off connections, and a grounding publish.
Outfitted with an influence provide first developed for the flagship RA180 amplifier, the RA280 performs optimally in each state of affairs. The Silicon Carbide FET know-how employed within the energy provide supplies excessive output effectively with low warmth era, responding effectively to energy supply fluctuations with its 2.5kW class PFC circuit and high-capacity condenser.
With its big selection of options, applied sciences, and connectivity choices, the RA280 appears poised to stay as much as the expectations already set by its siblings.
The HiFi Rose RA280 is out there in black or silver finishes with an SRP of £2,999.
