There is a significant audible difference. I'm not exactly sure how one would define it apart from 'stronger'. Perhaps the nasalisation is only partial coarticulation at the end of a vowel, when followed by 'n'.
 
True historical nasalisation in final position is reduced to partial / light in the dialect I have studied, ie it has fallen in with dependant nasalisation.
 
I'll have to do some more thinking.
 
I wished to show the difference but I am still unsure how to tackle this phonetic issue.

What is the audible difference exactly?

I'm aware of two kinds of vowel nasalization.  Nasalization
throughout the vowel (as in French), or nasalization of the
final part of the vowel (as in Portuguese or Polish).  There
is no standard way in IPA to distinguish between the two.
