Walmart, 97 cents, for Vibration Control

As for cheap vibration control my go-to are Howie’s hockey pucks sold on eBay. Don’t get the cheap junky practice pucks. Splurge and get the 100% rubber game pucks! Otherwise, I use the John Darko approved audiophile doorstops sold on Amazon. 

+1 OP.

This is why I have Walmart+.  Free shipping!

You could even put em on tree roots!  MC

They'll work as well as cable elevators, tuning dots, those Shakti wooden things, tube buffers, etc.

But are they audiophile grade fuzzy stick black pipe cleaner thingies? Just curious....😂😁 this is right up there with the rubber bands as cable elevator tweaks...and just as cheap! How can one loose? I’ve heard of using Marshmallows on top of amplifiers can help absorb spurious micro vibrations until they melt....tried it once, what a mess. Also, too much carbon dioxide in your listening room can cause the air to become dense and affect sound waves. I solve this by holding my breath while listening and somtimes I  alleviate this issue altogether by habitually pumping copious amounts of helium into the room.
