'such hi-fi would have been' is the definition.
I can't tell whether this defines the answer.

'right for an old peruvian' is the wordplay.
'right' becomes 'r' (common abbreviation).
'for' means one lot of letters go next to another (I've seen this in other clues).
'an old peruvian' becomes 'inca' (the Inca were a historical people of Peru).
'r' after 'inca' is 'IN-CAR'.
