Quiz about adding dense mass to a vibration isolation application!

There are two steps in this quiz:

1) Hypothetically, you have a DAC that is very solidly built on all sides and weighs 25 lbs.

This DAC currently has three Nobsound vibration isolation devices under it, the springs of which are about 50% compacted and are damped by foam ear plugs inserted inside of them.  The vibration isolation effect with this setup is merely middling according to a cell phone seismograph app.

2) You add a 25 lb granite slab to the top of the DAC with a 1/8-inch rubber mat between it and the DAC, and then add the appropriate number of ear plug foam damped springs to each Nobsound device in order to get all Nobsound device springs back to about 50% compacted.

The question: What do you think is the sonic result of step 2?

I tried it once, but may have gone a tad overboard...

JW:

 

My electronics are located outside the listening room (in a hall closet located behind the speaker wall in the living room).

 

I drilled 4 small holes through the double wall to run speaker cable to the living room.

 

Various footers and shelves placed under my TT/CD decks do alter the sound (same with a DAC when I used a seperate one).

 

You can experiment with items you probably already have around the home...

 

For soft footers cut up an old mouse pad.

 

For hard footers try matching ramekins, shot glasses, bat gammon pucks (you get the idea).

 

I finally ended leaving the gear stock (footer wise) and placing them on specialty shelves custom made for my rack.

 

Tried EAR, Mapleshade, Racing Cone, et cetera, footers, but never tried springs.
