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?
@jerryg123 Glad to be of service ! @bugredmachine Finally…somebody who knows what a shaker table is ! i always dread that first test of a stacked payload and buss. Not because i thought hardware would fail but because as the “ shop guy “ clouds of FOD , etc often…appeared .. NAIM components isolate the IEC inlet :-) For the cable guys, activated carbon open cell foam makes an inexpensive and effective cable riser. Jim
