@mlsstl Good Point! Will listen to the two songs that it happened on again...

Finally got around to swapping L and R at the preamp outputs. Lo and behold the pumping motion also swapped from the R speaker to the L speaker. I always listen with grill covers off. If I left them on I would never have noticed. On the extremely rare occasion when it happens, I just turn the volume down. |
@tomcarr Its very obvious the problem is either the preamp or your source. |
Hello @atmasphere ! I don't think it's the pre or the source because I've had two different preamps, and two different sources, and it has happened with both configurations. It only happens when listening to two songs, out of the thousands of songs I listen to. I'm of the opinion that there is some subsonic bass buried in those specific recordings. Thanks to all for your opinions! |
