High-performance hybrid amplification from HiFi Rose
HiFi Rose’s RA280 integrated amp has features and looks that straddle the line between modern and classic. It resembles its bigger, more expensive sibling — the flagship RA180. The RA280 uses the same hybrid amplification technology, an innovative design that HiFi Rose calls “Class AD.” Like most Class D amps, it uses a “switching” design. But its GaN (gallium nitride) FET topology sweetens the sound by speeding up the timing between switches — up to 10 times faster than typical silicon FET switching devices.
High-quality design and build
You can see this amp’s top-notch design and build-quality inside and out. Its solid aluminum and steel chassis with integrated heat sinks contribute to its hefty 20+-pound weight. And it uses dual-mono 250-watt amplifiers with isolated circuitry and premium components for unassailable sound and near-imperceptible noise and distortion.
Product highlights:
- stereo integrated amp with balanced and phono inputs
- Class AD amplification uses super-efficient GaN (Gallium nitride) FET output switching for smooth, accurate sound
