There is nothing wrong with the K3 audio on the whole. It is one of the
best receive audio's I have listened to. Audio is always subjective. I
prefer a slightly higher audio as I find it easier to hear at those
frequencies. To say one thing is better than the other is at best
really only going to be *your* opinion. Others have said they do not
like the audio at all while I find it great at the default settings. My
post was purely to show that there are some unwanted artifacts in the
receive audio chain. As for transformers colouring the audio through
saturation, that simply should not be happening, at least at these kind
of levels!
