"I wonder how you could have "over-damped" the chassis or components to sound flat"
In engineering, when you damp a system you can damp it so that it's in one of three states:
-- under-damped - this is where the system still oscillates, but less
-- critically damped - where the system returns to normal as fast as possible with no oscillation.
-- over-damped - here the system does not oscillate but returns to normal slower than the critically damped case
See https://en.wikipedia.org/wiki/Damping, but this is basic mech eng.
So it's entirely possible to overdamp something, and the effect is that the damping is slower than is needs to be. Car suspension for example is designed to be critically damped - if you overdamp the car will not drive as well, with bumps unsettling the vehicle for longer than needed.
Imagine a loud bass drum crash with a subtle cymbal (say) shortly following. On an overdamped system you may get the effect of the cymbal being lost due to the slow damping action.
Also note that critical damping relates to a particular (resonant) frequency, so that a system that is critically damped for say a bass drum frequency will be over-damped for higher frequencies.

my resorting to "Well, I just overdid it!"I would imagine someone with skills much beyond mine could actually
tune a chassis to get optimum results for their ears. I suppose it's akin
to tube dampening where if one applies too many dampers and/or places
one in the "wrong" position you can easily change the sonic characteristic
of the tube and null the good vibrations.Speaking of tubes, I like what the magic tubes do/have done so far (in
your recommended IC usage) but have yet to have the chance to experiment
or assess enough to post about it.Thank you!
