I have a problem and I was hoping that I could have some advice on this. My receiver shuts off all of a sudden and once I turn it back on it says check speaker wires. I have swapped out different pairs and have noticed that as long as I do not use one wire the problem disappears. However, why would this happen since I am unsure how a cable can be shorting itself out or have I simply gotten the problem wrong and it may be something else even though it has stopped. Your opinions are much appreciated. I am using Audioquest Bedrock purchased from AudioAdvisor.
