Isolation vs. Absorbtion

I am new to the audiophile hobby, and I am confused by what appears to be subjectivity and contradictions. When "mounting" a cd player and other components, is it best to use Soft Pads which ISOLATE vibration and RETAIN internal component vibration, OR is it best to use Hard Cones, which DRAIN (harmful) component vibrations into shelf material. Secondly, is it best to attach shelving to racks so that shelving makes Direct (hard) Contact - OR, should the shelving be Isolated from rack? Is there a scientific, indisputable answer?

Not to get off topic, but Sean what tweaks did you make to your Justa-Rack. I have two of these and I found your comments very interesting. - Dan

Redkiwi, Sorry I am confused again. I think this thread is great. Please clarify this for me... You said don't MDF if you can at all help it, but if you must use MDF (as I have to in my MGD JustaRacks) then use hard damped cones between the MDF and the component? Or assuming that the MDF shelf is still in the system, can you put a shelf like the Neuance on top of the MDF separate them (Neuance shelf and MDF shelf) by hard damped cones and then use the e-a-r feet between the Nuance shelf and the component? Is this close to what you have found? - Dan

Thanks DeKay. Good to know that I will not have to replace my MDF with other material. So did you spike the maple directly into the MDF or did you use a plate of some kind to keep the spikes from embedding themselves? - Dan

Red and Dekay, Do you think a Seismic Sink would also work in isolating the Neuance Shelf from MDF or does it make things worse? I have my CAL Delta on top of the Sink now. - Dan

I second Dekay's last post. If it is a custom shelf then please post the details for the benefit of all. I have a MGD (metal threaded rods with the MDF Shelves) and maybe I could replace the MDF shelves with the Neuance Shelves with a little tweaking. Do you think that would be light a rigid enough?
