HiFi Rose RA280: The Class D That Makes the Heart (and Foot!) Beat<\/h2>\n

If you think Class D<\/strong> is synonymous with cold and mechanical sound, get ready to change your mind! The Audio 2G team has put the new HiFi Rose RA280<\/strong> to the test, an integrated amplifier that’s making waves, and we’re here to tell you all about it.<\/p>\n

A Design That Speaks<\/h2>\n

Forget anonymous luxury. The RA280 presents itself with a *bold personality*, a mix of impeccable finishes and striking details:<\/p>\n

    \n
  • The input selector<\/strong>, a truly “forcibly analog” piece that adds a vintage touch.<\/li>\n
  • The small VU-meters<\/strong>, “polite” and functional, reminding us of what’s happening.<\/li>\n
  • The illuminated tone controls<\/strong>, a detail that makes a difference.<\/li>\n
  • The “beautiful top grills,” adding a notable aesthetic touch.<\/li>\n<\/ul>\n

    Functionality: Simple but Effective<\/h2>\n

    The RA280 integrates a Wi-Fi module, but beware: it’s not a streamer<\/strong>. So what’s it for?<\/p>\n

      \n
    • OTA software updates<\/strong>: Very convenient, especially for those who dislike complicated procedures.<\/li>\n
    • Control via app<\/strong>: The app only controls the volume and does not allow input changes (which are mechanical). Giulio wonders if that Wi-Fi module was really necessary.<\/li>\n
    • Physical remote control<\/strong> is a pleasant surprise: small, ergonomic, and not the usual rebranded remote.<\/li>\n<\/ul>\n

      Connectivity: The Return to Analog<\/h3>\n

      This amplifier is “almost completely analog,” reminiscent of the good old days. We find:<\/p>\n

        \n
      • 3 line inputs<\/li>\n
      • 1 Phono MM input<\/li>\n
      • 1 balanced XLR input<\/li>\n<\/ul>\n

        Not many, but what you need is there<\/strong>. And the tone controls<\/strong>? Present, bypassable, and done “very well.”<\/p>\n

        The Technological Heart: GaN and Revolutionary Class D<\/h2>\n

        The real beating heart of the RA280 is its innovative Class D<\/strong>. Forget the old modules: HiFi Rose has developed its own architecture, based on Gallium Nitride (GaN) semiconductors<\/strong>.<\/p>\n

        During the “dissection” (opening to analyze the inside), impressive details emerged:<\/p>\n

          \n
        • A milled cover<\/strong> in 4 mm thick aluminum.<\/li>\n
        • Proprietary amplification modules with GaN<\/strong> strategically positioned.<\/li>\n
        • Coilcraft flat film output inductors<\/strong>, among the best for Class D.<\/li>\n
        • An extremely oversized switching power supply<\/strong>, with two separate power supplies.<\/li>\n
        • The VU-meters<\/strong>, indicating the input signal and not the power delivered.<\/li>\n<\/ul>\n

          Sound Performance: Speed, Rhythm, and Engagement<\/h2>\n

          And now, the part that interests us most: how does it sound<\/strong>? Giulio’s impressions were enthusiastic:<\/p>\n

          \n

          “It really convinced and gave goosebumps!”<\/p>\n<\/blockquote>\n

          The RA280 boasts a remarkable delivery capacity<\/strong>, handling even the most demanding genres with disarming ease. The extreme speed<\/strong> typical of Class D is expressed here with “feeling,” never sounding mechanical.<\/p>\n

          The strong point? The sense of rhythm<\/strong>. It reminded us of high-end amplifiers, capable of making you tap your foot and engage you in the sound event<\/strong>.<\/p>\n

          The only note: the timbre is slightly too dry. It requires careful pairing with speakers to avoid a sense of “harshness.”<\/p>\n

          The Comparison: Class D vs. Class A\/B<\/h2>\n

          Giancarlo noticed a huge difference: while Class A\/B appeared “a bit awkward,” the RA280 “darts,” showing superiority in terms of driving and rhythm.<\/p>\n

          Conclusions: Exceptional Value<\/h2>\n

          At a list price of \u20ac3200 in January 2026, the HiFi Rose RA280 offers *incredible* power and driving capability. Despite its 9.5 kg, half of which is casing, this amplifier challenges conventions.<\/p>\n

          The GaN<\/strong> technology is opening new frontiers for Class D, and the RA280 is proof of that. If you’re looking for an amplifier around \u20ac3000 and aren’t tied to vintage sounds, this is a product to seriously consider<\/strong>.<\/p>\n
