Im leaving tiresome clapped-out hi-fi system (6)
I believe the answer is:
stereo
'hi-fi system' is the definition.
(I've seen this in another clue)
'im leaving tiresome clapped-out' is the wordplay.
'leaving' suggests deleting specific letters.
'clapped-out' indicates anagramming the letters.
'tiresome' with 'im' taken away is 'tresoe'.
'tresoe' is an anagram of 'STEREO'.
(Other definitions for stereo that I've seen before include "In-depth" , "Means of amplification of sound through two or more channels" , "Three dimensional sound effect" , "A 19 player" , "Sound transmitted through two speakers" .)
