There's lots of things like those pucks that will work to improve sound. Then there's things like springs that work a whole lot better. With springs you can go two ways: cheap and pretty good, or expensive and amazingly good.
Cheap and pretty good are Nobsound, only $30 for a set of four. These replaced BDR Cones and Round Things that cost ten times as much, and the BDR was the best of all the cone/spike/stiff type footers. With Nobsound you will hear improved imaging, greater detail with less glare, blacker backgrounds and more depth. Bass will be greatly improved, and a lot less of that bass energy will go into the floor so less sound transmission to other rooms and especially less to your turntable.
With Townshend you could put Pods between your stand and the speaker, or put the whole thing on Podiums. John Hannant at Townshend can help you figure out which way to go with that. With either of these you will hear the same improvements as Nobsound, only with greatly improved bass that is much tighter and more smooth and accurate, and a huge improvement in the tone and timbre of individual instruments. A guitar sounds so much more like a guitar, and not only that but the type of guitar, type of strings on the guitar, and if its a pick or fingers plucking the strings. Just takes everything springs do and ups the game with a whole lot more refinement. They do this by being really well engineered with just the right amount of damping in proportion to being freely suspended.
Look at my system.
https://systems.audiogon.com/systems/8367 I am big on vibration control. Have been for 30 years. Have tried a whole lot of stuff. These are the two best options, and I use both in my system. (Need to update pics, sorry! Townshend Pods are now under turntable and amp. Nobsound and other springs everywhere else.)
