The new RA180
Absolute Pure Sound Integrated Amplifier. The RA180 is a state-of-the-art integrated amplifier using the latest innovative technologies. Power damping and dead times were reduced to 1/10 or less. Linearity was dramatically improved to create a near-perfect sound that transcends the boundaries between digital and analogue. Enjoy the pure sound of nature provided by the RA180.
New Concept Class – AD Amplifier
The amplifier has developed from Class A to AB to Class D Class AB was developed to improve the high heat generation and low efficiency of A. Class D has higher efficiency and higher output than AB, and also significantly improved S/N and THD characteristics compared to A and AB. However, the sound quality has been evaluated as inferior to A/AB due to the limitations of the digital circuit. The GaN class AD amplifier developed by HiFi ROSE has dramatically improved the problems of the existing Class D by applying innovative new materials,
Balanced Power Supply
The power supply that has been exclusively developed for the RA180 applies 4th generation SiC FET technology to provide high output with less heat. In addition, by using a self-developed PFC (power factor circuit), it is designed not to be affected by sudden load fluctuations. The power supply device was developed to support a powerful damping factor of at least 200 and the high output of 1000 W is designed to produce powerful bass and soft treble
PHONO Amplifier with Variable EQ
The purpose of the PHONO amplifier provided by the RA180 is for the recording producer to accurately reproduce the original intention. It also reproduces the original sound as it is, which is the principle of HiFi ROSE. It is designed to respond to a variety of vinyl records with low-mid bass TURNOVER and high-frequency ROLL OFF adjustment functions. Amplifies the very weak signal picked up by the cartridge and keeps it as close as possible to the original sound. MOVING MAGNET and MOVING COIL STAGES are provided with a simple switch selection and EQ values corresponding to curves from various record manufacturers are provided using parts with a 0.1% tolerance
