model S307 "sparkling" - Mini Integrated Amplifier

Compared with small transistors, high power transistors tend to be unfocused and low resolution in sound character. So we felt necessity of making a tiny power amplifier enough to listen to musics in an ordinary living room. By selecting a high performance device from many BJT in overseas and Japan, we developed this ultimate 3W amplifier. Incredible clear, sparkling and natural sound.


Ultimate 3W - Enough to enjoy music in your living room.

With this tiny and cute amplifier (same size as model S304), you can enjoy broadcasting and BGM in your living room. 2 x 3W (8Ω) fully discrete BJT amplifier.

4 inputs selectable - Immediately listen to music with a simple operation.

This includes 4 input selector and volume control. You just connect music source such as CD player and loudspeaklers.
