SQ606
Commentary

This pre-main amplifier was released as a popular type that allows you to enjoy the sound of Lux more easily.

The basic configuration is the same as that of SQ505. Only the auxiliary circuit of the pre-part has a different structure. In addition, by changing the acceptance criteria of the parts, the configuration is almost the same but the cost is reduced.
