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.
