In my experience, connector differences can easily be heard. Generalities such as silver is one way and gold another can also be changed based on the quality of the actual base metals. Homegrown Audio offers connectors at a good price, though I find the Furutech spades to be much better. I don't think you can go wrong with the Furutech 201(G). To my surprise, I actually liked the 201(R) better. My surprise, because I generally find rhodium to be etched and un-musical, but Furutech's are not. The Oyaide spades are also exceptional performers.
