This amplifier combination consists of the LM-512CA preamplifier and the two LM-503PA mono power amplifiers used for the left and right channel respectively. Especially distinctive is the volume control of the preamplifier, which is laid out like a watch dial. The pointer, moving clockwise, indicates the volume level. The arrangement of the tubes is oriented to the layout of a Chinese garden. When they light up, an area of light and shadow becomes visible on the metal plate of the amplifier, creating an appeal of its own. Regardless of music style, the electronic tubes produce warm, rich sound.
