HiFi Rose RA180 Integrated Amplifier

HiFi Rose's RA180 redefines the intersection of vintage aesthetics and cutting-edge technology, presenting a new era of integrated amplifiers that elevate your auditory experience; boasting illuminated meters, a sleek silver chassis, and gleaming sliders and switches, it seamlessly blends retro and futuristic design elements, while its engineering ensures an expansive frequency response beyond human hearing for a captivatingly immersive soundstage.

Employing the latest in amplifier technology, the RA180 features AMP modules tailored for stable bass and balance, each supporting 200W (8 Ohms) and combining for an impressive total output of 800 watts; its unique Bi-Amping configuration, including a Bridge Tied Loads (BTL) mode, provides enhanced driving force without succumbing to back electromotive force.

Equipped with built-in moving-magnet (MM) and moving-coil (MC) phono stages, the RA180 caters to vinyl enthusiasts with adjustable EQ and precision-tuned curves corresponding to various record manufacturers, ensuring an authentic analog experience.

The adoption of Gallium Nitride (GaN) Advanced Class D amplifier technology by HiFi Rose revolutionizes the limitations of traditional Class D designs, delivering a near-perfect linear output, smooth, and natural sound akin to an analog amplifier; this innovation addresses the shortcomings of Silicon FET technology, introducing a groundbreaking level of linearity and fidelity.

Addressing the upper limit of human hearing, the RA180 features an extended frequency response range of 20Hz - 50KHz, reaching up to 100KHz@-3dB and 200KHz @-6dB, ensuring high-resolution sound sources are faithfully reproduced, contributing to a rich and realistic sonic expression.

The balanced power supply, incorporating fourth-generation Silicon Carbide (SiC) FET technology, enables high output with minimal heat generation, while the self-developed power factor circuit ensures stability against sudden load fluctuations, supporting a powerful damping factor and a high output of 1,000 watts for deep bass and accurate treble tones. In essence, the HiFi Rose RA180 is not just an amplifier; it's a harmonious blend of timeless aesthetics and state-of-the-art audio engineering.
