I use TX equalisation with my K3 to improve on my deep gravelly voice. 
It sounds far better than my TS-480 with a similar microphone on both 
transceivers (Kenwood MC-43S on the K3, stock mic on the '480), the 
TS-480 has limited equalisation on TX but even with that it's well below 
the quality of the K3 audio which sounds to my ears close to as good as 
it's going to get from my voice. Unsolicited reports on the quality of 
my K3 TX audio are commonplace and I've never received reports such as 
those at any time in my 37 years of operating... I don't think there is 
anything wrong with the K3 TX audio.

On receive the only "quality" receiver I have for comparison is a Drake 
R4A and the K3 sounds better than that, and the R4A isn't at all 
unpleasant to listen to... The Drake meets specification and has new 
smoothing capacitors... The K3 receiver has an open sound which can 
sound harsh when combined with a lot of background hash in the form of 
white noise from a typical domestic situation where you are surrounded 
by houses with computers, switched mode PSUs, etc. Under clean band 
conditions that openness sounds great when listening to SSB with the 
same DSP bandwidth as the roofing filter (2.8 KHz in my case). I use no 
equalisation on receive.

Bottom line to me is the K3's audio is fine. And no, I'm not on 
commission from Elecraft!
