Covers for racks to keep dust off?

Nope. I just use a swifter once in a while. I think my turntable comes with a dust cover… if so, it is still in the box.

I just had quilted covers made for my components.

No need to mock the OP.  He wants to take care of his gear. Unhelpful sarcastic comments like this, especially to a new member, are so inappropriate.

Matt, there is an outfit that makes custom covers as noted above. My wife custom made some cheap covers out of black fleece type fabric that is soft and won't scratch.

I also agree that Swiffers are a must have.
