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.

Features

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.
