Another Hum question

So I just noticed a slight hiss / hum coming from both speakers, both drivers in each. Left speakers hum is slightly louder. I disconnected everything from the amp and it's still there. The only way I've been able to get it to quiet down is by hitting the switch on the back of the amp from unbalanced to balanced, and then there's no hum, just a very very slight hiss from the tweeters that I could live with. The amp is a classe ca 150. Any thoughts? Thanks for any input!!

So am I okay just using xlr's, or do I need to fix the ground loop problem?

Xti 16,
Thanks for the reply! I was also told that I could try getting a cheater adapter thst goes from a three prong to a two prong, but I've also heard not to do that, as it may be dangerous?

Jea 48,
I stumbled upon that very site lastnight. It was a little above my head, but I'll read it again and try to figure it out! Thanks.
