A Business You can Trust

In 2005, we started the audio workshop Music Infinity. We’ve been developing and making tube amplifiers and bookshelf speakers all these years.

It’s been 15 years since the M20A integrated tube amplifier’s debut. You can still see her on the production line today. It’s a true classic. Now we can expect the Spotless A1 amplifier will be the new flagship.

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.
