[Elecraft] K3 Hissy and Noisy Audio

Is what you call "hissy" just a lack of bass? I think of "hissy" as high 
pitched white noise, like wind blowing through a narrow pipe. Is that what 
you hear? Adding low freq. audio won't reduce hiss at all but I don't think 
we are dealing with hiss. I think the lack of bass gives us the perception 
of a tinny, narrow sound, not hiss.
