It seems that there is a case of Apples and Oranges here.
The OP was more about Phase Noise that is emitted by the Radio. 

Here is Wayne's response to the OP. 
BTW, Jim's call should be K9YC as Wayne corrected later. 

( See W9YC's study of transmit phase noise and keying bandwidth of various transceivers:   http://audiosystemsgroup.com/TXNoise.pdf )

If the K3 were supplied with a stock microphone, rather than leaving it to
the purchaser to potentially make a poor choice and then not bother to
compensate with the equaliser, I believe we wouldn't be reading these
admittedly  isolated comments about K3s with "thin audio".  This has
recently come up again with the current dxpedition in Iran.

I probably make fewer than a dozen SSB QSOs in a year, yet when I do I am
almost always complimented on the audio.  I am using the MH2 microphone.
