recabling my Stax sr-009 to pure copper cable

Hi!

I got a pair of headphones that's original uses silverplated copper. I can hear the side effect of the silverplated copper gives (forward, hot treble) i also miss some low midrange (100-400hz).

This is kinda silverplated copper vs copper thread. But do you guys think that recabling my headphone to copper would give some extra low mids compared to silverplated copper?
