How important is the rack you use for your components


I’ve been browsing thru people’s systems on audiogon and have seen all different kinds of racks, shelves, bookcases , stands etc. For people’s equipment. My question is how important is the rack to the sound of the system. Has anyone gone from a basic rack to a premium and/or home constructed rack and noticed a marked improvement? And when I say marked, I mean marked. Looking for input

Prof sorry but wrong, We have been playing with isolation devices for both electronics, and digital components for years and the difference is very audible.

All electronics are sensitive to vibration and that includes solid state as well as tubes. Of course Turntables are a greatly improved by isolation.

I used to do a demo of a $900 Rega Planet on a solid steel shelf, then with Black diamond footers, and then a black diamond shelf.

The black diamond shelf is a thick slab of carbon fiber with other high density plastics. and a set of carbon fiber footers.

I would demonstrate this cd player vs a $3000 Cd player booth on top of the same racks, then put the isolation components under the Rega once the CD player was fully isolated it crushed the performance of the more expensive cd player and once you took the cheaper player off of the base and then put the better player on top viola the more expensive player then wildly outperformed the cheaper one.

Think of mechanical jitter, this way in the days before electronic image statbilzation and you were trying to take a long aperture exposure with a telephoto lens the small shakes and vibrations would cause your exposure to be blurry.

A $20k professional camera  hand held vs a $1k camera with the same lens setup but sitting  on a tripod would take a much sharper picture, then the much more expensive camera.

All devices including transistors are microphonic, tube are more so, but transistors still have crystaline structures which can vibrate.

When you remove vibration the system focuses much better, the images are much more defined, bass is tighter. Huge improvements.

If you told me 10 years ago I would have a $14k Stillpoints rack I would say your are crazy. The difference putting high end electronics just amps on this rack were huge.

We recommend Isoacoustics cheap and very effective.

We are looking at several next generation racks as Stillpoints have gotten crazy expensive but you have to hear the differences in doing proper vibration isolation it takes a good system into the next generation.

The methodology is playing the same music for two to three mins adding or subtracting what you are testing and listening for differences.

The thought I heard a difference is repeatable with other listeners then you have consenus. We have always found that many others have varrified our findings.

If you get yourself away for the conspiracy effect, there are tons of reviewer who have heard the differences that power cords, high end cabling, vibration and isolation products and of course room tuning. 

Check out all the articles on Acoustic System Resonators way too many people have heard them work effectively.

We setup a system with them in the 2013 New York Audio Show, Waterfall Audio's designer was there, he heard the products effect and was amazed at the difference. 

For a lark pay $60 bucks and purchase three boxes of Isoacoustics footers and try them under a component and see what you hear.

I guarantee you will be doubting me no more Prof.

Prof there have been many companies who had done accelerometer testing of the components on and off of their racks over the years which have demonstrated that these devices do work.

In the case of the resonators, there was a Germany company I think FAST was the distributor who paid for an indepth study of the resonators and their testing showed beyond a shadow of a doubt that the resonators affected a change in the energy spectra of the room.

Science is a wonderful thing, please explain the differences to a gas chromatograph of a bottle of 1954 Chateau Lefeat Roscheld. at $10,000.00 a bottle and a bottle of your favorites whinos $1.99 bottle of ripple.

You and I can easily taste the difference the machines would report water, organic materials, but the difference in the two traces would be probably 99.9 percent identical.

How do you measure a difference in tightness and dynamics, when the apparent differences might not show up in a frequency response curve or an spl meter.

It is the feeling you get when a the product hits you in the right way.

Sceptisim is a good thing, but there are times that you need to let your ears by your guide.

By the scientific explanation a 3 foot power cord that is connected to a house full of Romex shouldn't make a difference but it does.
