I would take a listen to a K3 on ssb mode and compare it to others
before deciding.

A flat RX equaliser setting sounds terrible with aggressive white noise
on my K3, using good quality headphones and/or ext speakers.

The pink noise roll off setting for RX equaliser as per ;

http://n1eu.com/K3/K3_notes.htm

Red settings made the difference I can live with along with agc settings;

AGC THR  =   8
AGC SLP   =   2
AGC DCY  = soft
AGC S       = 15
AGC F       = 80
AGC HLD  =  0.2
AGC PLS   = NOR

RX Equaliser (This is what really makes the difference to me)

50hz = +16  100hz = +6  200hz = +2  400hz = 0  800hz = -1  1600hz = -3  
2400hz = -5  3200hz = -10

Using RF gain reduction to reduce noise against audio level is
beneficial until NR is required.

Also recommend the 1.8k 8 pole ssb filter with 1.6~1.8 k rx bandwidth
settings.
