isolation

I think it is the most worried about problem in all of audio. The differences I have heard are insignificant or minor at most and no my hearing isn't damaged . The isolation choices and looks are great, the thick wood or stone slabs, the brass spikes, the gel pad,air pillows, Hocy pucks, racing carbon fiber rooling balls , miniature shock absobers all give the audiophile yet another way to spend a lot of money. The best isolation is to really go all out mass loaded RMI RFI and gamma irradiation proof. Thus dig a bomb shelter in your base or build at least 100 yards from any potential vibration. Have a very meticulous builder who knows how perilous vibration is make the shelter at least 4 feet thick on all sides using alternating layers of cement, copper, silver, Bbubble wrap big bubble inly, rubber and cement each layer about a half inch thick repeatedly until 4ft, thick use a small dor size made from the same embed all electric wiring cable etc through the walls the carefully put each component on a steel platform supported by a solid lead block use stel and lead to make a cover over each piece. It cost a lot but it was worthit the toughest thing is dipping the specker cables in molten glass and lead connecting them at over 10,000 pounds each was a bear. But now I can honestly say the black is blacker now the system is much clearer the bass is dynamic and punch yet musical. I am hearing things in the music I never knew were there, and that darned freight train sound I had all the time is gone.

lol. I just finished building my hometheater room if only i had known.

People can try to explain this away however much they want.. Fact is that a good platform (or rack) does wonders to most equipment. The differences are NOT subtle in my experience.

Just because you can't find a logical explanation for why things improve sound, doesn't mean it's not there. Science may be good for some things, but it has no place in the listening experience.

A good isolation system can make a big difference in a high resolution system.It can enhance the illusion of reality and increase one's enjoyment factor,or it can rob the music of life and deaden things.
The best that I have tried is the Finite Elemente Master Reference system in combo with the cerabase feet.
Supports tend to sound like what they are made of--a good reason to avoid funky synthetic materials and stick to wood and steels.
