What causes a chirp?

I find changing the battery in the smoke detector eliminates this chirp!

....voiceboil Was funnier, though..made me think of quiet annoyance rising to a crescendo of rage.  Made me stop to consider where I've seen that....

Oh, yeah...the 'whose cables' better' forums...;)

If it happens around the same time of day, in my HT setup it's the off peak hot water mains signal coming through the system.

Tell us more about the chirp. When does it happen? What is the frequency of it happening? What is the duration? Is it from one speaker or both? Do you have any tubes in your system?
