I think all of the esteemed replies so far have been accurate but fail to take in to account "alternate facts".
Its 2017 and we now live in the time of facts, which haven't changed, and "alternate facts" which apparently can be whatever you need to fit a situation.
The alternate facts world states plainly that putting pieces of wood underneath your equipment can tune it and give you more and better bass, warmer sound, clearer treble, or lighten up the entire system. All with putting different flavors of wood underneath your components. This alternate world of facts is bravely and ably explained and represented on

A small quote perhaps will help fill in some alternate facts and help the OP understand 2017 audio tuning.
"Mounting your audio gear on a really good platform transforms the sound. Our painstaking R&D tests proved that maple platforms sound warmer, clearer, punchier and more detailed than granite, slate or glass (all are edgy and bass-killing), hi-tech damped composites (very dead sounding), and myrtle or exotic hardwoods (more colored and less detailed). Thats confirmed unequivocably by more than a decade of head-to-head shootoffs by skeptical customers. Using brass footers to drain vibration out of your gear into the maple doubles the good effect."
Of course, if you choose to stick with old school facts, the stuff that's been around for 1/2 century or more, then as long as the stand doesn't vibrate, it doesn't make a dang big of difference what your gear sits on. I realize that's not exciting or insightful. Be sure to clear your browser cache after visiting a website like mapleshade. It might cause your computer to start vibrating. They have product to fix that of course.
