Rotel RB-1590

Core Performance Specs

• Power Output: 350 Watts per channel into 8 Ohms (both channels driven).

• High Current Delivery: It remains stable at 4 Ohms (pushing nearly 650 Watts), making it ideal for speakers with difficult impedance dips (like MartinLogan electrostatics or large B&W floorstanders).
• Dual Monoblock Layout: Internally, the circuit is laid out as two separate mono amplifiers. This ensures maximum channel separation and a wider, more precise stereo image.
• Power Supply: It features twin, massive custom-made toroidal transformers and eight British-made BHC "slit-foil" capacitors. These provide the "instant" energy needed for explosive musical transients and deep, controlled bass.
