[CAUT] Full Cover w/ DC

[Andrew Anderson]

Why not add an undercover to the package.  That should get you some 
isolation from what is coming through the floor.  Then you can keep 
the full system without it becoming an eyesore.  Unplug the 
humidifier side until winter, or better just keep it going.  I like 
string-covers for stability and damping ultra high frequencies.  A 
full cover is a lot of work to put on and remove, are they actually doing it?
