[Elecraft] Taming the SSB receive dragon

I have only had the K3 for a few days and have already experienced a
couple of headaches from listening to hours and hours of SSB in rag
chews and nets on 75 meters. When compared to my trusty Kenwood TS-480,
the K3's receiver was far too harsh.
I process the receive audio through a Behringer mixer panel and into a
pair of Behringer Ms40 speakers - hence, both radios get the exact same
chance at sounding really good.
I did some research into the problem and read what other ops had done to
correct the problem. Then I applied those gleanings to my K3:
I run the 2.7 filter open (full WIDTH)
I set the SHIFT to 1.3 (mellows things out a little)
The AGC SLP is set to 15 (this slayed the wow-wow dragon)
The AFX Delay at 2 (can change with the mood)
RX EQ: +3 +3 +2 0 +1 +1 +1 -1 (you can play with this forever)
Now I have that wonderful Kenwood receive audio back. Couple that with
the arsenal of the K3's QRM/QRN tools afforded by the DSP and a 2.1
filter - and I can hear through almost anything. I am impressed with the
K3 - it is a keeper - affording fine listening quality.
There are two more receive dislikes I will be working at getting rid of:
1. General background hiss - which is more noticeable on the K3 than the
480 (even using the ATT and reducing the RF Gain). I live in a quiet
rural location - it should be quieter than it is.
2. The NOTCH (auto) - introduces an unpleasant variation to the signal -
specifically, a slight warble.
I am open to suggestions and comments.
