Musician III SE II

About the Musician III SE II

The Spectron Musician III SE Mk II is a Class D stereo power amplifier designed for audiophiles seeking both high power and refined sound quality. It delivers 600 watts per channel into 8 ohms, 800 watts into 4 ohms, and up to 1400 watts into 2 ohms, with peak current capability of 50 amps. The amplifier features a fast closed-loop feedback system for low distortion (<0.03% THD+N at full output), a damping ratio of 400:1 to tightly control speaker drivers, and a frequency response of 20 Hz to 20 kHz within ±0.1 dB. It is stable into very low impedances (down to 0.1 ohm), making it suitable for demanding loudspeakers including planar and electrostatic types. The power supply uses a large bank of capacitors (33,000 µF total) to provide low output impedance and high transient headroom. Inputs include balanced XLR and single-ended RCA, with Cardas binding posts and Neutrik Speakon outputs. The amplifier runs cool with high efficiency (>92%) and includes fold-back current limiting to protect speakers and amplifier from damage. It weighs 52 pounds and measures 17" W x 5.25" H x 14" D. The The Musician III SE Mk II is praised for its ability to drive difficult speakers to very high volumes with clarity and low distortion, making it a reference-quality amplifier for serious audiophiles.
