The Line Magnetic LM-216IA is a vacuum tube integrated amplifier known for offering heavy-duty audiophile performance at an approachable price point. Built around Western Electric-inspired topologies, it uses a push-pull Class AB design paired with KT88 power tubes.
Core Features & Design Highlights
-
On-the-Fly Mode Switch: A front-panel toggle lets you switch between two distinct sonic signatures:
- Triode Mode (22W): Softer, sweeter, and more textured midrange. Ideal for acoustic tracks, jazz, and vocal-heavy genres.
- Ultra-Linear Mode (38W): Delivers greater power, punch, dynamic headroom, and tighter bass. Suited for rock, orchestral pieces, or driving harder-to-power speakers.
- Integrated Bias Adjustment: Built directly into the top panel. It features an illuminated VU meter and individual trim pots for each KT88 tube, allowing manual bias calibration without needing a multimeter.
-
SoftStart & Time-Delay Protection: Automatically waits ~30 seconds upon startup before applying full voltage to extend tube life.
-
Premium Parts: Includes point-to-point hand wiring, an ALPS motorized volume potentiometer, and Realcap coupling capacitors.
- Machined Remote Control: Ships with a heavy aluminum remote to control basic volume and mute features.
