A handmade audio manufacturer recognized by professionals

Do you know what a "vacuum tube amplifier" is?
These great-sounding amplifiers are used by audiophiles and guitar players who are particular about sound. Some people may be dreaming of using one someday.

The vacuum tube amplifiers used by audiophiles are large, heavy, expensive, difficult to handle, and do not necessarily produce good sound. They are difficult to come by, out of reach. We have condensed the goodness of such vacuum tube amplifiers into a palm-sized device.
Even if you're not interested in audio, if you love music and want to enjoy music with good sound quality, we recommend MHaudio's compact hybrid vacuum tube amplifier, the UA-1.

The UA-1 is a vacuum tube amplifier that uses vacuum tubes, a nostalgic yet sound-oriented electronic device, and condenses the sound of real vacuum tubes and the authentic form and construction of an audio amplifier into a compact, practical size.
Not only does it have a great tone, but the three-dimensional design, presence, and feel of the instrument will give you enjoyment that goes beyond just using it as a tool for listening to music.
