Description

The RC-1590 stereo preamplifier is a high-end preamplifier designed for the highest levels of audio performance and is ideally complemented by the Rotel RB-1590 power amplifier. Its goal is to deliver top-notch performance with any type of music and give the user maximum flexibility in choosing sources. As is Rotel tradition, the utmost importance in design and implementation is given to the power supply, and in fact this unit features two Toroi power supplies.dali Rotel itself manufactures oversized amplifiers, one for the analog section and the other for the digital section, thus combining efficiency with the necessary isolation between analog and digital signals. The RC-1590 is also fully featured, with balanced XLR and unbalanced RCA inputs and outputs, a precision volume control, a fixed-volume line output, and subwoofer outputs. dual mono, digital outputs (coaxial and optical), digital inputs (3 coaxial and 3 optical), internal Bluetooth aptX that supports aptX and standard Bluetooth with an external antenna mounted on the rear, a front USB socket for iPod. On the rear panel there is a USB port for PC/Mac that feeds a 32-bit/768 kHz digital converter and also supports DSD and DoP. Finally, the front panel houses a 3,5 mm headphone socket. It is noteworthy that the analog and digital circuits were designed separately by specialized Rotel teams. All these functions are logically controlled by the included remote control and visible on the beautiful front display.

About the brand

Rotel is a Japanese hi-fi brand founded in 1961 that represents excellence in high fidelity through a perfect balance of traditional English craftsmanship and technological innovation. With over 60 years of experience in the audio industry, the company has established itself as a benchmark for discerning audiophiles, offering superior audio electronics in the mid- to high-end segments of the international hi-fi market.
Rotel's corporate philosophy is based on fundamental principles that have guided the company since its inception: the pursuit of sonic purity through simple and elegant circuitry, the use of meticulously selected high-quality components, and a manufacturing process that combines industrial precision with artisanal attention. The company motto, "Balanced Design Approach," reflects this vision, where every element of the stereo system is designed to work in perfect harmony with the other components. The company has always prioritized substance over appearance, focusing on listening quality rather than purely aesthetic elements, a philosophy that has won over generations of music lovers and international critics.
Rotel's signature technologies include proprietary high-current Class AB circuitry featuring toroidal transformersdali Oversized power supplies ensure a stable, interference-free power supply. Direct DC coupling eliminates capacitors in the signal path, preserving the purity and dynamics of the original audio. Rotel Link technology allows seamless integration between different components of the same series, while advanced protection circuits safeguard both the electronics and the connected speakers. Particular attention is paid to electrical shielding.romagnetics and the internal arrangement of the components to minimize mutual interference.
The Rotel product line includes reference-level transistor integrated amplifiers for the hi-fi market, stereo and monoblock power amplifiers for high-end pre- and power amplifier configurations, preamplifiers with MM/MC phono stages for analog turntables, CD/SACD/DVD players with state-of-the-art proprietary DACs, and digital processors for modern source devices. Each category maintains the tonal consistency that is hallmark of Rotel sound, characterized by balanced, detailed, and musically engaging reproduction.
The A12 Series represents Rotel's entry into the world of integrated transistor amplifiers, delivering 60 watts per channel and class-leading sound quality. The A14 Series delivers greater power and refinement with 80 watts, while the prestigious Michi Series tops the line with electronics that utilize aerospace-grade technology and hand-selected components. Bookshelf and floorstanding speakers in the range complete the offering for complete audio systems, specifically designed to showcase the capabilities of Rotel electronics.
Rotel has received numerous accolades from the international audiophile press, including awards from What Hi-Fi, Stereophile, Hi-Fi News, and major European audiophile magazines.
