The HiFi Rose RA180 is a state of the art integrated amplifier that uses all of HiFi Rose's latest knowledge and technology to produce their best amplifier ever, along with one of the best integrated amplifiers on the market today.
Through HiFi Rose's dedication to progress, they've made significant strides with their advanced class D amplifier technology to generate an amp that has near perfect linearity, resulting in a sound that perfectly balances the analog and digital domain.
New Generation Class AD Amplifier
A true revolution in the world of amplification, Rose HiFi unveils an innovative Class AD architecture taking advantage of both the benefits of Class A/AB amplifiers and Class D structures. This particular design allows for improved linearity, in particular through the use of a new material, GaN (Gallium Nitride).
Furthermore, the RA180 opens the doors to bi-amplification by integrating four independent amplifier modules. Each module supports a response up to 100kHz, allowing the use of super tweeter.
To power these modules, the RA180 features a massive power stage capable of delivering 1100W of power to meet the needs of the most demanding audio systems.
FET Gallium Nitride (GaN)
In terms of power amplifier design, the Class D topology theoretically offers full linear output at 0% distortion and 100% efficiency. To achieve this theoretical perfection, the speed and accuracy of switching operations must be secured.
To correct this concern, the RA180 features a perfectly linear output using a Gallium Nitride FET instead of a silicon FET which directly affects the switching accuracy and speed. This fully linear output exceeds the capabilities of the Class D topology and allows for a natural sound reproduction, close to that of an analog amplifier.
Four new mono amplifier modules
The RA180 offers a stereo output and provides two channels for each right and left output. Each amplifier offers a power of 200W under 4Ω and 8Ω, allowing a bi-
