Rotel RC-1590MKII. High-Performance Stereo Preamplifier
High-fidelity sound systems deserve components that meet their demanding standards. The Rotel RC-1590MKII is exactly that—a reference-grade stereo preamplifier engineered to deliver a natural, precise, and deeply musical presentation across both analog and digital sources.
Dual Power Supply Design for Ultimate Signal Purity
At its heart lies a sophisticated power supply featuring two custom-designed toroidal transformers, built in-house by Rotel. These transformers are physically and electrically isolated to provide dedicated, clean power to the most sensitive analog and digital circuitry. High-grade low-ESR slit-foil capacitors are used to reduce unwanted distortion and achieve an ultra-low noise floor.
Audiophile-Grade Digital Conversion
Digital inputs are handled by a high-end Texas Instruments DAC, capable of 32-bit / 384 kHz processing. This is paired with a custom-tuned output filter stage, refined through extensive listening, ensuring playback that is precise, detailed, and three-dimensional, with pinpoint placement of voices and instruments within the soundstage.
Optimized Signal Paths for Maximum Fidelity
For analog sources, the RC-1590MKII includes a DIRECT-PATH mode that bypasses unnecessary circuitry, preserving the original signal integrity and further reducing noise and distortion. This obsessive attention to design detail results in a listening experience that is immersive, emotional, and true to the source.
