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.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eYou 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.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eThe RA280 has three line-level stereo RCA inputs, plus one RCA phono input for a turntable with a moving magnet cartridges. It also has a balanced stereo XLR input for making a low-noise connection to a high-end source component. All connections are analog, but you can get amazing sound from digital sources that have a built-in DAC — like the HiFi Rose RS250A network streamer.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eThe power supply inside the RA280 is specifically designed to stay efficient and high speed even under complex loads. HiFi Rose used silicon carbide FETs instead of the standard Silicon FETs in other power supplies. These high-tech devices have high voltage and heat resistance, allowing the power supply to supply maximum power while remaining efficient and cool. This well-designed power supply also applies a 2.5kW power factor correction circuit with a high-capacity condenser to maintain top performance at all loads while keeping stable and reliable.\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cbr\u003eThe RA280 uses a next-gen advanced Class D design developed in-house to take the acoustic performance of traditional Class D amps to a higher level. HiFi Rose calls this tech Class AD. Class D amps are considered much more efficient than traditional Class AB amps, but most have a pretty harsh and edgy sound. HiFi Rose’s Advanced Class AD design resolves these problems with new, innovative materials. The switching output devices are the enemy of sound quality in these high-efficiency designs. Dead time and a slower switching speed can cause noise and distortions to the audio and were responsible for the noise and gritty-sounding nature of early class D designs. Using GaN over traditional silicon transistors allows the switching speed to be much faster, allowing a dead time of 1\/10 of silicon transistors. This gives these new class D amplifiers a linear response, allowing them to have a natural, smooth sound quality that aligns more with class A amplifier designs.\u003c\/span\u003e\u003cbr\u003e\u003cb\u003e\u003c\/b\u003e\u003cbr\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif;
