[Elecraft] Noise Blankers

I'm overdue for a new radio (at least, that's what I am telling my
XYL). In considering the purchase, unfortunately one of the major
considerations I must take into account is
the noise blanker function. I have recently moved to an area with A LOT
of power line noise. I have high voltage lines around my immediate QTH.
It is a constant S3 to S5 on all bands above 7 MHz and, sometimes on
really
cold mornings, a seperate, additional noise kicks in that takes it to
S9 or more. I am trying to locate these noise sources but have been
unable to so far. I must run the noise blanker on my old TS-850s at all times to help me manage this problem. With the NB engaged (which
is 'always') I have audio distortion created from nearby signals,
especially stronger  signals within 30
kc's of my receive frequency, no matter at what level I run either of the noise
blankers. 

I would like to hear from K3 owners who might have
'line noise problems' and know how the noise blanker in your K3 handles
the problem.
