Moor Amps Angel 4 Dual Mono Power Amplifier


Moor Amps extend their low-feedback philosophy to the power supplies. The low-feedback Amplifier is fed with incredibly pure, high current DC rails from low-feedback regulators.

The heavy machined casing uses different panel thicknesses to damp each other out and avoid vibration reaching the Amplifier components.

The highly linear output stage uses 4 ring-emitter transistors to share the current load and remain linear, even when supplying large currents to keep a grip on the Speakers.

The Angel-4 combines the world of pure low-feedback with the high output currents needed to deliver the whole authentic musical performance. It delivers musicality and subtlety along with power, scale and dynamics. It delivers Music!
