Linn LK140 Power Amplifier

Overview

The Linn LK140 is a compact yet powerful stereo power amplifier designed for high-performance audio systems. Delivering 95 watts per channel into 8 ohms and 140 watts into 4 ohms, it offers both strength and clarity. Internally, it uses a toroidal transformer, direct-coupled architecture, and servo-controlled circuitry to ensure low distortion and precise sound reproduction. With auto signal sensing, the amplifier powers on when a signal is detected and enters standby when idle, optimising energy efficiency. Its solid construction is ideal for stacking with other Linn components, and built-in protection circuits guard against thermal and overload issues.
