RC-1590 MKII

Reference audio systems deserve reference audio equipment. The Rotel RC-1590MKII is exactly that - a reference preamplifier rending analog and digital sources with natural expression in a wide and open sound stage in stunning clarity.

The RC-1590MKII proudly continues Rotel’s 60-year legacy and heritage with their ongoing promises of performance, value, and unwavering commitment to quality. Authentic, engaging, and spacious – the RC-1590MKII proudly represents this iconic brand.

The heart of the RC-1590MKII begins with the power supply featuring dual in-house manufacture toroidal transformers. The transformers are physically and electrically isolated supplying dedicated analog and digital supply voltages to all critical circuits through low ESR slit-foil capacitors eliminating unwanted distortion and an extremely low noise floor.

Digital source inputs are processed utilizing an audiophile-grade Texas Instruments 32-bit/384kHz Digital to Audio Converter (DAC) with custom-engineered, proprietary acoustically tuned external output filter circuits rendering even the finest details with exceptional clarity and exact positing.

Analog signal paths feature DIRECT-PATH bypass modes eliminating unnecessary circuits maintaining signal integrity and further eliminating unwanted noise and distortion drawing you even closer and immersing you in the music.

The RC-1590MKII supports a full array of inputs ensuring connection to your favorite sources including a Moving Magnet Phono input for vinyl lovers, Analog, Digital, XLR Balanced, high-quality aptXTM and AAC wireless Bluetooth, and PC-USB (32-bit/384kHz) supporting MQA unfolding and rendering as well as certified Roon Tested.

Dual RCA and XLR output connections provide the ultimate flexibility including bi-amplification installations. A subwoofer output is also included.
