Why are equipment racks so expensive?

“Am I willing to spend the money, reorganize my gear, and take the time to listen for the (possible) subtle improvements in sound?

Nope. Too lazy for that.”

Then why bother with the rant! Are you bored?

+1, @ozzy62 for Butcher Block Acoustics recommendation. 

"You certainly must do your research, but high quality audio racks can be considered a component. Not if you have $500 components, but if you have $10K or higher...."
So a $500 component isn't worthy of isolation?
Glad you told me, I just about the waste my money on a top quality rack.
Can't understand why some people think that audiophiles are elitist.

Reading through this thread has certainly opened my eyes. Now that I think about it, we took an old lawnmower motor, ran an old fan belt to an axle, we were able to drive all around the neighborhood. Why then does a Porsche Turbo cost $200k? 

@ozzy62 , lay instinct is rubbish. How the f do you think an F22 would fly if electronics were sensitive to vibration. A targeting computer has a lot more to do than your silly DAC. The Russians were using tube electronics in their airplanes up to the early 70's. Worked just fine. You guys are hysterical. Knock yourselves out.

A few months ago I made a rack inspired by this thread: 

https://forum.audiogon.com/discussions/built-a-diy-butcher-block-and-iron-pipe-rack-over-the-weekend

I'm really happy with results. It's as solid as a tank -- weighing more than a 100 lbs. I like the rustic and retro look very much, but it wasn't as easy to build as I thought it would be. Drilling precise holes through thick butcher block requires tools and wood skills. The cost of materials was around $500. The shelves are 1.5-inch thick and the legs are 3/4-inch plumbing pipe. You can see it in my system: https://systems.audiogon.com/systems/2056

After building this, it made me realize how much time and effort goes into building high quality furniture.
