Regards to the Rack

I've been a builder for a long time. I mostly work with stone, so call me a mason if you want to assign a name. As with any type of building, the foundation dertermines the performance and layout of each consecutive layer.

So I come to my point. Recently I have entertained purchasing an equipment rack that costs more than my CDP. The justification-the foundation plays a larger role in performance than I previously thought. Before I was content with an uneven antique credenza but now I have begun to believe that foundation is the answer to allowing components to perform to their potential even if the cost is significant.

The question is here, are there others who share similar opinions of the fundamentals of foundation or am I just off my rocker to think I'll get that much more noticable preformance from a rack? Well no need to answer the latter part really, I am an audio-nut so we already know the answer there.

If you are familiar with stone, have you considered building your own equipment rack? I've been considering building a rack with granite for some time. Just need to find the time. The stone will cost approximately $125 per slab with holes drilled. A tad cheaper with no holes.
I built one with slate, check my system.

The ninety day home trial period with some "footers" ideas from
Herbiesaudiolab.com
should allow you to use your existing furniture, at the same time experiencing a significant audible upgrade. It will give you a baseline of vibration control, against which to compare any future special rack purchase. Or, you can retain Herbie's ideas even with a rack.
His products seem to work well in every application where I have tried them. There are a few variations in his line to allow for tweaking the tweak.
And, the cost of his products is very reasonable.

Thank you all. I have been away for quite some time and just got to looking at this thread. Great suggestions all around. That was definately on question I had, how does grantite line up as an audio rack product. I mean I can get loads of granite for almost nothing and I have used it for my equipment, even went so far as to make a custom granite stand for my TT. But then I read granite only exaggerates the vibrations. Anybodt know about this?

Tim, nice rack!!

Again, thanks for the suggestions all. I will consider them closely.

Agree with the previous posters who praise the Grand Prix Audio Monaco Modular rack & amp stands - NOT a subtle improvement over my old Target racks, and worth every penny once one has invested significantly in their system. Be sure to fill the uprights w/lead shot for best results.

Plus, to my eyes...they look waaaay cool.

Ric Cummins at Argent Audio provided me with this recipe for resonance control platforms.

2"X2" sandwich footers of 1/4" plexiglas/posterboard/plexiglas

beneath

1" or 2" granite or marble

mismatched Timken bearing/cups between component and stone

The Timken bearing part numbers are

LM11910 raceway cup
09067 bearing

I've never tried this recipe due to rack space limitations. I have played with the Timken bearings themselves for footers and my results were mixed. I suspect using the full recipe would yield outstanding results. E.B. Atmus was the cheapest source for the Timken bearing parts that I found. If I had such a favorable arrangement regarding granite availability and pricing, I'd give Ric's plan a whirl personally. If it doesn't quite turn out to be your cup of tea I believe you could tweak further with Herbies Audio Lab products. I'd recommend this in either event actually.
