Congrats on the new system... and a great "first light" report.

For the buzzing armoire, is it possible to stop the buzz by placing your hand on the panel from the inside ? If so, could you jimmy up something like a brick or dumbell weight wrapped in thin foam and put it on a shelf INSIDE the armoire as a short term fix ?

I deal with "the little voice" by turning the stereo up a little louder. That has allowed me to remain very happy with my system in its current form
