[Elecraft] K3S subreceiver sound "problem"

[Vic Rosenthal]

If the a/b switch causes the problem to move, then it is something connected to bandwidth (etc.) settings and not a hardware issue with the subrx. The a/b switch doesn’t change which receiver goes to which ear (etc.)

When I listen to both receivers through good quality headphones, the subreceiver sounds muffled, dull, maybe a bit less volume when the gain and audio settings are identical, all the while the main receiver is crisp and clear. Reversing the head phones reverses the effect which, I think, rules out my hearing and hearing aids.  Reversing things with the A/B switch makes the left channel muffled and dull. I've tried a whole lot of different setup parameters, read the manual and Cady's book carefully, but I can't come up with anything the brightens up the subreceiver. Any suggestions?
