[Elecraft] Impact of this mod: K3 I.F. Output Buffer Gain Modification???

[Jack Berry]

Can someone explain the real world value of making this modification? This mod 
is listed on the Elecraft website with this description (new production 
incorporates this mod):

This modification increases the signal level at the I.F. output by more than 10 
dB. It requires changing one
easily-accessible resistor on the K3’s main RF board with either another surface 
mount device (SMD) or a leaded
1/8 watt resistor.
I have s/n #3012 and expect my radio was pre-modification. I will be adding 
filters and other mods after the first of the year and want to make this is one 
time affair if possible.

Merry Christmas!
