Here's a Weird one

I put on my Isotek CD track 2 and played it in the CDP, through the DAC and passive line stage ,volume high, but with both power amps off so no sound through the speakers.

But at a few points on the track noise could be heard from the tweeters on the right speaker. I listened more closely and the left does also put out a little but perhaps only 10% as much or even less.

Since the DAC outputs 2.5VRMS @50 ohms I guess I can understand a little something getting through the amp even turned off but I don't know why it is so unequal. Some cap more charged than another? So as a test I paused the CD and turned on the HF amp for one minute, then off, waited 10 seconds and unpaused the disc. It was equal on the left the next time something was heard. So a cap on the right probably holding a charge longer?
