Looks like quality connectors and overall reliability. I won't know for sure until I use it for a long time, so it's mostly about the looks. In terms of sound quality, I don't think anyone can notice a difference while it's running. I use it to extend the temperature sensor and the readings are the same with or without the signal going through that wire.
