Rotel RC-1590 MKII Stereo Preamplifier

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

Manufacturer Details:

The heart of the RC-1590MKII begins with the power supply featuring dual in-house manufactured toroidal transformers. The transformers are physically and electronically 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 utilising an audiophile grade Texas Instruments 32-bit/384kHz Digital to Analogue Converter (DAC) with custom engineered, proprietary acoustically tuned external output filter circuits rendering even the finest details with exceptional clarity and exact positing.

Engineered With Care:

Analogue 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-1590 MKII supports a full array of inputs ensuring connection to your favourite sources including a Moving Magnet Phono input for vinyl lovers, Analogue, 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.

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