Unsure of which one you are referring to Dennis? For clarification where audio signals pass through either contacts or electronic volume controls there is typically deterioration of the resulting audio.
LDR's are quite different altogether, being a passive variable resistor, arranged in a L pad, activated by more or less light intensity. There are no contacts as light is a contact less medium.
The differences of one LDR product to the next are explained here:
