Graziano,
How are you measuring the power output in SSB? If an external
wattmeter, you are likely driving it to full PEP power.
I test the SSB operation on each K2 I repair to be certain the PEP is
the same as the CW response at full power. I use an oscilloscope to
determine that. An external wattmeter will only show about 50 to 60% of
the full PEP.
Run the SSB C menu parameter to 3:1 and try it. If you are using an
electret microphone (Elecraft or Icom), the SSB A parameter at 1 should
be sufficient, but if using a dynamic microphone, a setting of 2 is good
for the higher output microphones but 3 may be needed for those with low
output.

The K2 have only SSB and CW.
Althoug in CW is the better, in SSB maybe not.
I agree with you that "strangely" the audio from the K2 is nicer despite the
tight filter, but i still find difficult to push out ALL the watt in SSB.
Comparing the K2 to my other radios, included the K3s, i can see that the K2
never reach the maximum output power in SSB. I tried different microphone and
settings, but i always get no more than 60-70% of the maximum power in the best
conditions.
This is the only point of regret with my beloved K2.
