I'm not familiar with SR5, but the peak at 1600Hz MAY be deliberate: this
has been used by some to increase readability in voice channels, though, not
sure if this is good in the presence of high noise as on HF.

Subject: [Elecraft] K3 Flat Audio?
Someone kindly mentioned SR5 here so I downloaded it and observed that my
audio from the K3 had a pronounced peak around 1600 Hz. I compensated for
this by adjusting the K3's RX equalizer so that EQ (6) is -4db, EQ (7)
is -4db and EQ (8) is -2db. I now have a flat response across the
spectrum. QRN is less distracting now. Also, my waterfall on MIxw is nice
and even all the way across now. This isn't very scientific. I was just
using band noise to adjust the EQ for a flat response but since band noise
is what I'm dealing with, I felt it was adequate.
Question is: Has anyone else noticed this? Do you think it's something to
do with filter shape? Maybe the audio amp. is indeed flat but the filters
aren't and I'm compensating for them. Whatever....I'm just glad there K3
has that nice EQ!
