I'm a new used K2 owner. I have been getting use to the rig the last week.
In another thread this was said:

I have used Spectogram to align the filters, and I'll be doing that again with a
bit more experience. That made a significant difference in the "feel/sound" of
the radio. Like you, I intend to do some more "measurement" in addition to just
setting things up and starting to operate.
Compared to the FT990, a rig that I have really enjoyed for many reasons, the K2
is much quieter and more flexible.

I have noticed I'm having the opposite experience. I have a noise floor of S9 on
40m. With my TS-430S and the ssb filter I can listen to the rig all day. But
with the K2 after a half hour or so I have to turn the sound down to give my
ears a break. There seems to be so many highs in the background noise that it
really gets on my nerves in a short time. This is even with the MFJ DSP filter
inline after the K2.
I don't have the dead tree manuals yet, maybe later this week. So I haven't
wanted to really get into checking all the adjustments until then.
The rig is dead on frequency, when replying to a cw station. On ssb I am told my
transmitted signal has great audio, MC42 hand mike. Power out is good. So, I'm
jumping to the conclusion that it's all set up well. What gives with all the
annoying highs even when using the cw narrow filters? Only relief I get is when
I turn the AF1 on.
I did use the spectrogram to move the cw center frequency from 500hz to 600hz.
When I did this, I happened to set it up on the wrong side of the passband. A
couple of folks got me straightened out on that. But the thing I remember was
how wonderfully quiet the rig was when I was on the wrong side. Signals just
popped up from the quiet and it was a pleasure to hear.
Any suggestions why I'm hearing so many highs? And how I might could shift
things around to change it when I get the manuals.
TIA
