HiFi ROSE RA 280 Integrated Amplifier Silver

HiFi Rose RA280 – High-End Stereo Integrated Amplifier Silver

The HiFi Rose RA280 combines powerful amplifier technology with an exceptional design and consistently analog signal processing. As a modern stereo integrated amplifier, the RA280 is aimed at discerning music lovers who value high performance, precise control, and natural music reproduction.

Unlike HiFi Rose’s well-known network streamers, the RA280 focuses entirely on analog amplification . It deliberately omits an integrated DAC or streaming unit. This makes the RA280 ideally suited as a powerful amplifier hub when used in combination with a high-quality external network streamer or DAC.

Modern GaN-FET Class-AD amplifier technology

The heart of the RA280 is a Class-AD amplifier stage with GaN-FET technology developed by HiFi Rose.

Gallium nitride transistors enable very fast switching operations and a particularly short dead time. This allows the amplifier circuit to combine high power output with high efficiency.

The power amplifier is designed as a high-performance dual-mono circuit and delivers superior control even with demanding loudspeakers.

Powerful and controlled playback

The RA280 was designed for dynamic yet controlled music reproduction. The high power output of the amplifier enables a confident sound reproduction with pronounced dynamics and high control over the connected speakers.

The RA280 combines the efficiency of modern switching amplifiers with a particularly smooth and natural sound reproduction characteristic.

Complex power supply

A specially developed power supply forms the basis for the high-performance power amplifier. HiFi Rose relies on an in-house design using silicon carbide technology , which is designed for high efficiency and a stable power supply to the amplifier circuit.

Thanks to its efficient amplifier architecture, the RA280 remains relatively compact despite its high power output and generates significantly less heat during operation than many classic high-performance amplifiers.

Purely analog signal processing

The RA280 is built entirely with analog components. It deliberately omits an integrated DAC, network streamer, or digital input stages.

Several analog line inputs, a balanced XLR input , and an integrated phono preamplifier for MM cartridges are available.

This makes the RA280 particularly suitable for listeners who want to individually select their digital source and combine it with a high-quality external DAC or streamer.

High-quality phono input

The RA280 also offers an integrated solution for vinyl enthusiasts. The phono input is designed for moving magnet cartridges and allows for a direct connection of a turntable to the amplifier.

The phono section is fully integrated into the analog concept of the RA280 and offers a high-quality solution for playing records.

Individual sound tuning

The RA280 features a classic, yet versatile tone control for bass and treble .

The corresponding controls allow the playback to be adjusted to personal preferences or the acoustic properties of the listening room. For the most unadulterated signal processing, the tone controls can be completely bypassed.

Analog VU meters

Visually, the RA280 is one of the most striking amplifiers in its class.

The two illuminated analog VU meters indicate the level of the two channels and give the device a modern high-end look with classic hi-fi elements.

The lighting can be adjusted in several stages or completely deactivated.

High-quality workmanship

The RA280’s housing combines a robust construction with the characteristic HiFi Rose design. The aluminum front panel and precisely crafted controls convey a high-quality and distinctive impression.

The large volume control, input selector switch and separate tone controls allow for direct and intuitive operation.

Subwoofer output

A mono RCA output is available for integrating an active subwoofer.

This means the RA280 can easily be combined with a high-quality 2.1 system without having to forgo classic stereo playback via the main speakers.
