Line Magnetic LM-34IA Tube Integrated Amplifier

The Line Magnetic LM-34IA is a push-pull, Class AB tube integrated amplifier with four EL34 output tubes and 2×40 watts of output power.

Why the LM-34IA?

The EL34 is regarded as the classic, British-European-flavoured amplifier tube – warm, musical, never intrusive. Line Magnetic runs it in Class AB and adds a soft-start circuit as well as an infrared remote control – a level of comfort you don't automatically get with tube amplifiers in this price class.

What you hear

A round, pleasant midrange, typical of EL34 circuits, with enough power for most living-room speakers and point-to-point wiring inside.

Who is the LM-34IA for? (and who it isn't)

For listeners looking for the classic, warm EL34 tube sound. Straight talk: if you want maximum control into difficult speaker loads, you're better served by a solid-state power amp – the LM-34IA plays to its strengths with normal 4- to 8-ohm speakers.

Our verdict

An integrated amplifier with a classic EL34 soul and modern comforts like a remote control and soft-start.

Frequently asked questions

Does the LM-34IA have a remote control?

Yes, an infrared remote control for volume is included.

Does the LM-34IA have a headphone output?

No, for tube sound over headphones the LM-MINI 84IA from the same range is the better choice.

How long does break-in take?

Expect a few days of regular operation before the tubes and transformers settle in sonically.

What is the Pre-In input for?

It lets you bypass the preamp stage and feed the power amp directly – handy for an external preamp or a phono stage with its own volume control.
