Thanks for the suggestions.
The subreceiver is on MAIN.
I set the selectivity for about 2kx in both receivers so that they are
both using the basic SSB filters, ie no 400cps filter in the sub-. I
re-checked all signal processing switches [ie, NR, NB, ATN, etc] to make
sure they were the same. I set both receivers to the same frequency,
both band noise and signals. I checked the rcv equalization; I don't
think that the two receivers can be set up with different profiles, at
least I couldn't do it. I turned off my hearing aids [the audio
parameters of my hearing in both ears are pretty closely matched]. So,
slightly better suggesting that some of the dullness was mismatched
setup. However, the sub- is still duller than the main. It's like the
there's a high freq cut on the sub-. In some respects it sounds like
there's some audio distortion through the sub- that's not there in the
main. That's it for the moment.

I recently purchased an Elecraft assembled and tested K3S with a
subreceiver and its own 400cps filter. The main receiver has the
following filters: 2.8, 1.9, 500 & 200. 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?
Thanks.
