I've stayed out of this thread and have only skimmed it but I'll weigh
in a bit now.

I have very good hearing.  I listen to my K3 using high fidelity
headphones only - I never use the speaker.  I operate CW only.

My rig sounds very good.  I do have the Radio Shack level control
in-line with my Sony headphones (which are very sensitive) and if I run
the volume all the way up on the in-line level control, I get hiss from
the rig, but it has nothing to do with the K3.  Every device I listen to
with my Sony phones & the level control wide open (mixing boards, MP3
players, computers, stereo systems) produces hiss, and they all require
AF gain be kept very low.  Basically, since the phones are so sensitive,
I'm listening to the inherent noise floor.

The solution is simple.  Throttle back the in-line volume control and
the hiss goes away.  Turn up the AF gain (to a normal level) and you get
plenty of signal.

Great sound, no hiss - That's my K3.

My hearing aids do not have much response above 3.5 kHz.  If I do not
use the aids, my hearing drops off significantly above 1800 Hz although
my low end hearing is about normal for the general population.

I bow to those with better high end hearing than mine, but to me the K3
has no audio problems.  Therefore I will make no further comments on
this subject.
