I have been interested in the logic and pains some go to to "isolate" components from vibration. I will say at the start that I have NOT experimented, as that is not me. HOWEVER, here is what troubles me. IF vibrations are deleterious to certain components, it arrives at that component either directly through the air by sound waves, OR indirectly though the surface it sits on(and, of course, in the case of analog front end, the device itself creates vibration). I have seen and read of many different ways of minimizing these vibrations, both with mass(ie HUGE turntables), and vibration absorbers. What I havent see talked about, but have in my system, is everything (except amp and speakers) is enclosed in a huge, solid cabinet, which certainly helps with both of the sources of vibration...thoughts?
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?
