If it was a really old D-104 with the ceramic element, you may have made 
a wise decision. The elements were physically fragile and I would not 
buy one without testing it.

I'm using one and I have the audio gain range set to low. The Heil 
headset seems relatively insensitive, but I have not found a problem. My 
hearing is not so great (I'm old) but not damaged. The K3 high range is 
significantly greater than the K2 so it should be enough.

Yes there is a separate equalizer for rx and tx. I used the tx equalizer 
to sharpen up SSB audio a bit, and reports were good, but I don't use 
SSB much. I have the rx equalizer set just to give me a little mid-range 
gain for CW. Each equalizer has 8 frequency bands, and is pretty flexible.
