I'm not sure if sound clips will help you a lot, because each player/horn/mouthpiece/reed combination has it's own unique specific sound anyway.
But in general the combination of a Link (having a large to medium/large chamber size, depending on the model) with an old Conn (a sax with a wide bore) will work well, assuming that both horn and mouthpiece are in a good condition. Of course Otto Link produced many models and the modern Links are normally less good than older ones, but in general any well playing Link model will be a good combination with your Conn NW.
Here is a clip of Lester Young from 1936, when he played a Conn NW and 1930's Otto Link mouthpiece (a Four**** model in a 5 tip, having a huge chamber):

I play tested a Tranny Conn New Wonder from 1932 myself some years ago with different mouthpieces (amateur level) and preferred a 1940's Otto Link Tone Master. Here are two clips (the first one on the 40's Tone Master and the second one on four mouthpieces):
1. - 'It Don't Mean A Thing' (Conn NW- Otto Link Tone Master 8 - La Voz medium):
