SPU singer, whose full name is Stereo Pick-up Unit, is a representative product developed by Gao Feng Company after 1959 officially launched stereo vinyl records. Today, SPU series is still supported and loved by many vinyl fans.
From the early A-type with short needle pitch to the G-type developed for the new singing arm, it is generally called "whale head" because it looks like a whale. The stability of the timbre and the unforgettable sense of the scene all give fans a voice charm that other singers do not have.
SPU singers have developed for many years, and there are many classic productions, such as the familiar SPU A Synergy and SPU Gold in the early days, or today's Royal General MKII and limited edition SPU A95, all of which are desirable and even have great collection value.
