 For two reasons:
1. Heat rises and the first thing it will run into in the action cavity is 
the pinblock.
Heat doing what it does, with or with a humidistat, will over time cause 
premature failure of the pinblock.....this ain't rocket science. :-)
2. The DC installed in any area of the action cavity draws outside air into 
the cavity through convection as we would expect and verrrrry little of this 
'warmed' air will actually get to the jacks/balanciers...this makes any benefit 
from a cavity installed DC problematical at best. Because of the openess of 
the cavity/block/platewebbing/capo area there is never any sustained drying of 
anything...well except for the block.......

 No amount of "insulation" will stop the pinblock from drying out over time. 
The answer to this 'sluggishness' problem is to solve the real problem(s) and 
not treat the symptoms.........period.
My Opinion.
