I can definitely agree that the base metal and plating off connectors can change the sound signature. I have experienced lots of combo's. (phosphor bronze, tellurium copper or brass as base metal) and different kind off plating's (silver, gold, platinum, rhodium). It is a subtle effect though. Some can sound more detailed or cooler/warmer, but i have also found that some connectors change the dynamic envelope off the transients in a subtle way.
Some connectors focus more on the attack of a sound and some more on the sustain part. I think this is because of the changing resistance properties of the different layers of metal. I have AECO pure silver RCA connectors with Neotech nemoi-1220 silver occ. It gives a warm & detailed sound with an endless sustain on reverb sounds. Pure copper is also something to consider, if you like a more neutral sound signature.
KLEI or Eichmann for RCA is also a very good option. EIZZ has some nice XLR connectors with tellurium copper/platinum plating and screw terminals. Furutech has some nice XLR's for welding.
I have spend way to much money on cables and connectors, it is like audiophile nervosa ;) And if you are competent enough, DIY is the way to go and can save you a lot of money.
