About the LM-508IA

The Line Magnetic LM-508IA is a stereo integrated tube amplifier designed for audiophiles seeking high-fidelity sound with a classic single-ended Class A design. It uses high-quality 805 output tubes and 300B tubes as drivers, delivering 48 watts per channel into 8 ohms. The amplifier features point-to-point wiring, hand-made construction, and premium components such as Japanese ALPS motor potentiometer and Mundorf N-Cap capacitors. It supports multiple input options including 3 line inputs and 1 bypass input, and offers speaker output impedance options of 4, 8, and 16 ohms. The LM-508IA includes bias and hum balance adjustments accessible on the top panel, a soft start and time-delay circuit, and a metal removable tube guard cage. It also comes with an infrared remote control for volume and mute functions. The amplifier weighs approximately 40-42 kg and measures 430 x 420 x 270 mm. It operates on 230V power with a consumption of about 400W. The design emphasizes musicality and reliability with specially designed EI transformers and a high-pressure power supply with filament preheating to extend tube life.
