Why spend more than $25 per piece of equipment on vibration reduction?

In some cases, spending more is necessary to have a product that’s effective in isolating, decoupling or draining. Vibrapods have some isolating properties but also store resonances, therefore aren’t near as effective as more expensive, well thought out products. I’m a fan of springs and have over the years tried to make my own products using springs and have been impressed. Recently ordered some Townshend spring products after years of trying but not yet reaching the pinnacle of springs with proper damping.

Vibrapod cones are quite good.  I use them under my electronics.  That said, I use Still Points under my turntable.  

yes - magnetic levitation, air suspension

Still points are superior but at over $100 each expensive ,

better  then hockey pucks ,or vibrapods ,is from Herbies tube dampers 

his tall tenderfeet ,they are made of a special isomer from  Germany I have used these for years, very  good  for $16 don’t break the bank.

Vibrapods #1 to #5 along with their cones seems fine to me. I put the higher number vibrapod under the heaviest section of equipment, typically the transformer. Also use those rubber/cork sandwich squares which seem to work well. Lastly, I use numerous Butcher Block Acoustics supports, some with cones, some with adjustable rubber feet. They are economical supports and look nice as well.

The Vibrapod website has some nice tips and tutorials on how to use them properly, including how to utilize them in a vibrapod sandwich. I just don't see the need to spend much more on these things, I'm also on a concrete slab. Turntable resting on dedicated shelf  mounted to a concrete wall. No issues there.
