Key Features
The Rotel RB-1552 MKII is a stereo amplifier for home Hi Fi systems. Designed to boost your signal to your system's speakers, the RB-1552 MKII is best paired with a complimentary preamplifier for a rich, balanced sound. Since it offers two channels of clean 130 W power, the RB-1552 is an excellent entry point into high-end amplification.
The RB-1552 MKII's Class AB amplification design helps to eliminate crossover distortion and high efficiency, while still offering fantastic sound fidelity. This power amplifier utilises slit foil capacitors, which store a lot of reserve energy for more dynamic musical sections and recharge quickly, creating a natural, energetic sound signature. The inputs on this amplifier can be either XLR or RCA, making it easy to set your system up with any kind of speaker.

Rotel have created a power amplifier that is perfect for listening to more dense pieces, whether it be full orchestras, complex jazz compositions, or intense rock bands, the RB-1552 responds incredibly well to varying dynamics and intense transients that help to pull the emotion out of whatever material you want to hear.
Accepting inputs from balanced and unbalanced sources alike adds some versatility to this affordable power amplifier, letting you connect to any stereo preamplifier you might own before routing to your speakers.
Powered by a bank of slit-foil capacitors, the RB-1552 MKII is designed to respond more dynamically to high-energy music. The unique design of these capacitors allows them to store a large excess of energy that they're able to release during more intense sections of music, allowing them to reproduce thunderous percussion, loud guitars, or orchestras hitting crescendos and quickly recover to do it again.
