Where can I find 1/4 20 speaker spikes???
I looked all over for 1/4-20 spikes as an upgrade to the long, skinny ones that come with Skylan stands. Stumbled onto ones offered by Tekton which are exactly what I was looking for at a very reasonable price of $20 for a set of 8 plus $5 shippin... 
Bi-Wire with two pairs of speaker cables

Another vote for Swiffer dusters. 
Night and day speaker connection
audiosens,The improvement you heard by paralleling (aka, "shotgunning") the two speaker cables and jumpering at the speaker posts would indicate that the wire gauge used in your original biwire configuration was not adequate. There might be a slig...
