About the brand

> View Company Site

The makers of LM audio are extraordinary in every respect. This is not your typical Chinese audio manufacturer, this small company is located close to Hong Kong and is managed by two brothers with a passion for Western Electric amplifier designs. At the onset the brothers worked in repair and refurbishment of vintage tube amps but were so adept in the Western Electric tube designs that they formed a production company to further their own interest and designs.

In current production are some extraordinary Amplifiers, Integrated amps, D/A converters, Digital sources and also speakers using reproductions of legendary Western Electric drivers and horns.

They have built their company around a philosophy that in their own words: is not just a product but a way of life.

The dedication to this type of manufacturing, around vintage tube sound and circuitry is uncommon according to today’s manufacturing standards. These gentlemen spare no effort to attain their musical goal and have achieved what they refer to in their designs as “Art for the heart.”

Trippin’ on the Line Magnetic

By Tim Smith, Wall of sound

What was I hoping to hear? Power and finesse. Warm single ended triode tone with low bass and high headroom. The best of both worlds. Did I get my wish? OMG yes! This amp has found a permanent home. What’s the secret sauce? Those 845 power tubes, of course. The king of the valves. SET magic… Read more >


Coup de Foudre A specialty retailer in Montreal. They carry the Line Magnetic equipment. They demonstrated a speaker with a single full range driver that uses a magnetic field coil to manage the bass using two B300 outboard amps and driven by an LM 845 amp. The cabinet looks like a sort of half-size Tannoy… Read more >
