Product Description:

The Rotel RB-1590 is a high-powered Class AB stereo amplifier delivering 350 watts per channel into 8 ohms with both channels driven—an ideal solution for large listening spaces or low-sensitivity speakers that demand ample current for peak performance and lifelike dynamics.

At the core of the RB-1590 are two oversized toroidal transformers, custom-built by Rotel, supported by a robust power supply featuring eight British-made BHC capacitors known for their quick response and low energy loss. This architecture ensures consistent voltage and current delivery even under challenging load conditions. True to Rotel’s design philosophy, this amplifier prioritizes refinement and musical accuracy over brute force alone.

Every part has been selected through extensive listening evaluations, and the internal layout follows a true monoblock structure for enhanced channel separation and precise stereo imaging. Key features include both balanced XLR and unbalanced RCA inputs, dual pairs of 5-way speaker binding posts, 12V trigger input, comprehensive protection circuitry, a dual-stage power-on relay to reduce inrush current, and a detachable IEC power cord. Housed in a 5U chassis with included rack ears, the RB-1590 is built for serious audiophiles seeking uncompromised performance.
