We design, produce and distribute stereo amplifiers

In 2005, we started an audio workshop designing and making tube amplifiers and bookshelf speakers. In the same year, we launched the mini tube amplifier M01A and the bookshelf speaker M01S.

The following year, M20A integrated tube amplifier came into the market. It’s been 15 years since its 1st generation release. You can still see her on the production line today. It’s a true classic.

Spotless Audio


Spotless is an authentic, simple, approachable, and unpretentious brand of traditional handicrafts.

We believe in sticking to our ideas and original designs, injecting thoughts and emotions into every detail and every product, to give it more vitality. We don’t strive for perfection; we strive to hold the nostalgic mood and to interpret the artisanal sentiment of age, to the old traditional handicraft works, which remind us how to listen to the years’ footprints.

Whether auditory, visual, or tactile, our handicrafts will quietly wait for your heart to approach them, understand them, and feel them.

Spotless Seed Story

Story of Seed

What is the most powerful thing on the planet?

Some people say elephant, some say lion,
some joke that it is King Kong.

How much power King Kong has,
of course, we do not know.

In Spotless terms, the most powerful thing in the world
is the seed of a plant.

The power revealed by a seed is infinite.
