[Elecraft] Roofing Filters

[Brett Howard]

So in reading the inrad description of roofing filters at:

http://www.qth.com/inrad/roofing-filters.pdf

It seems that they all but tell you to buy the elecraft 5-pole filters when
talking about 500Hz and narrower bandwidths.  Does this hold true in the
case of the K3 in that the higer pole count results in a lower "roof" I
guess you could call it and then end up needing more gain in the next stage
therefore ending up with less dynamic range?
