Adequate exterior, if I get right part of hifi (9)
I believe the answer is:
amplifier
'hifi' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'adequate exterior if i get right' is the wordplay.
'adequate' becomes 'ample' (I've seen this before).
'exterior' indicates putting letters inside (some letters go on the outside of others).
'get right' becomes 'r' (I've seen this in other clues).
'if'+'i'='ifi'
'ample' going around 'ifi' is 'amplifie'.
'amplifie'+'r'='AMPLIFIER'
'part of' is the link.
Can you help me to learn more?
(Other definitions for amplifier that I've seen before include "Device augmenting sound" , "What Speaker may require" , "Sounds all up with this" , "Device that strengthens" , "Device to boost sound levels" .)
