Perfect opening we hear (5)

Ross

I believe the answer is:

whole

'perfect' is the definition.
(thesaurus)

'opening we hear' is the wordplay.
'opening' becomes 'hole' (hole is a kind of opening).
'we hear' indicates a 'sounds like' (homophone) clue.
'hole' sounds like 'WHOLE'.

(Other definitions for whole that I've seen before include "All the components" , "In entirety" , "undamaged" , "Total" , "Entire, undivided" .)

I've seen this clue in The Times.
