Audiophile's equipment (6)
I believe the answer is:
stereo
'audiophile's equipment' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for stereo that I've seen before include "Sound transmission through two or more speakers" , "Of sound equipment, having two speakers" , "Record player" , "Description of record" , "With twin audio channels" .)
