Line Magnetic LM-32DAC Tube DAC

The Line Magnetic LM-32DAC is a converter with an ESS9028Pro chip that plays through either a tube or a solid-state output stage, selectable at will.

Why the LM-32DAC?

Two output stages in one device: a switch toggles between tube (2× 12AU7) and solid-state, so you can choose the sound character to suit your mood and your system without swapping devices. Five digital inputs cover practically every source, from AES/EBU to asynchronous USB.

What you hear

One review calls the LM-32DAC a "capable digital converter at a reasonable price" with "excellent soundstaging" (Mark Gusew, StereoNET, October 2020) — warmer through the tube stage, more neutral and direct through solid-state.

Who is the LM-32DAC suited for? (and who isn't it for)

For anyone with several digital sources — computer, network player, TV — looking for a converter with a choice of character. Let's be direct: the LM-32DAC has no variable output — it definitely needs a preamp or integrated amplifier behind it.

Our verdict

A converter with genuine sonic choice instead of just one fixed character — confirmed by the trade press.

Frequently asked questions

Can I switch between tube and solid-state?

Yes, via a switch on the device — that lets you choose the sound character to match your system and your mood.

Does the LM-32DAC need an amplifier with volume control behind it?

Yes, the output is fixed and not variable — a preamp or integrated amplifier with its own volume control is essential.

Which formats does the LM-32DAC play?

PCM up to 32-bit/384 kHz and DSD256, across five different digital inputs.

Does the LM-32DAC have a headphone output?

No.
