I would say that, due to the design of XLR connectors and the nature of balanced operation, cables in general and connectors in particular have much less impact than with standard (single-ended) connections. There is simply less 'foo' with XLR. Therefore I don't expect the large differences I've heard from the single-ended 223.5 cables and I don't think there is any merit in going with, say, a Furutech XLR connector when the Neutrik is so well made and costs very little.

Sorry if my previous response seemed a little terse, I didn't mean it to come out that way
