I have had what some would call low audio out of serial number 26XX 
since new, 
to suit my tastes I drove a set of computer speakers that are amplified, 
and they
worked fair,  I have since changed to a set of Motorola speakers and an 
outboard
solid state stereo amp about 10 watts,  works great and the speakers 
have good
communications audio. 
Compared to several other brands of radios the K3 has much less audio 
"power"
than any of them,  not sure it there is a difference in K3s in the audio 
department
or if its just my old ears,  but I do not have enough audio to drive a 
set of speakers
off the radio to decent volume without an external amp. 
Headphone output is the same,  I have to crank up the audio and if using 
a narrow
filter and or DSP I do not have enough audio with the gain full open,  
thats with
Heil cans,  Yamaha cans,  and several others tested.  I plug the 
headphones into the
external amps output and switch between cans and speakers. 
I guess there could be a problem with my K3,  but have run into several 
others
who have similar results.   So I assume there are differences in the 
audio the same
as there is in the IF/RF gain between units. 
Nothing that bothers me with the external amp in line.   73 Merv K9FD
