The Iron Fist in a Velvet Glove The Moor Amps Angel-4i is a high-performance dual-mono integrated amplifier designed for listeners who demand absolute control and musical transparency. Hand-built in the UK, the Angel-4i embodies the Moor Amps philosophy: delivering massive current and effortless dynamics while maintaining a refined, fatigue-free sound. It is an amplifier that doesn’t just play music; it commands your loudspeakers with total authority.

Dual-Mono Precision To ensure maximum channel separation and a vast, holographic soundstage, the Angel-4i utilizes a true dual-mono architecture. By keeping the left and right channels entirely independent, the amplifier minimizes crosstalk and lowers the noise floor, allowing the finest micro-details of your recordings to emerge from a pitch-black background. Whether driving delicate acoustic monitors or demanding floorstanders, the Angel-4i remains unshakeable.

Effortless Power and Control While rated at a conservative 75W into 8 ohms, the Angel-4i effectively doubles its output to 150W into 4 ohms, demonstrating its immense current-delivery capabilities. This “stiff” power supply ensures that even during complex musical crescendos or deep bass transients, the amplifier never loses its grip on the drive units. The result is a sound that is muscular, agile, and startlingly lifelike.

Simple, Elegant Engineering The Angel-4i avoids unnecessary digital circuitry to preserve the purity of the analogue signal. Housed in a robust, understated chassis, it features high-quality RCA inputs and heavy-duty loudspeaker terminals that accommodate wired, spade, or 4mm plug connections. With built-in protections against short circuits, overloads, and temperature extremes, the Angel-4i is engineered to be the reliable, long-term heart of a world-class audio system.
