Right channel cuts out Please Help

I have a Portal Audio Panache and a Arcam cd72T. I have never had one bit of a problem with either of these devices since I have owned them.

Today I listened to about 3 cds while doing some homework and all of a sudden the right channel cut out completely. I went to see what had happened, but couldnt figure what the heck it could be. I checked the speaker cables quickly and the
interconnects. All seemed to be snuggly fit. I moved the balance control from side to side, and then the volume up and down, nothing. Then it just came back to life. There seemed to be no channel imbalance or distortion.
