Line Magnetic – LM-845iA Integrated Amplifier

From £3,999.00

The LM-845IA integrated amplifier is an evolution of Line Magnetic’s popular LM-518iA amplifier. Using 845 valves in a single ended design, it delivers 22 watts per channel in Class A.

The use of high quality components, EI transformers for power supply and output and isolated, point to point wiring ensures that this amplifier delivers great single ended sound from the 845 valves.

Bias adjustment is made easy with a built in meter.

The use of the legendary triode 845 offers a special listening experience and its power and current capacity allows the LM-845iA drive a very wide range of speakers.
