How important are spikes?

I tend to agree that isolation pucks and spikes are generally worthless, except for turntables obviously.

There is a good benefit to put in cushions under the feet of your subwoofers to avoid vibrating things in your room indirectly through the floor. And maybe some cushy feet under your main speakers for the same rationale. But to say there is discernible sonic improvement from all this isolation crap especially on components is just insane. Quintessential snake oil. Positive reinforcement benefits, most likely. I guess there is some value to that. If it makes you feel better go ahead and buy it.

I buy lots of stuff and even after trying it I’m willing to concede that it’s not a good idea to buy some of the stuff. I use sliders underneath my bookshelf speakers and under Center channel amplifier feet, because it’s easier to move them around. I also use acoustical tiles underneath my speaker feet so I can move them around more easier. Only 10 bucks a game changer for the tiles. Impresses people when it’s so easy to move around the speaker. Yes it's simply genius

Clearly, based upon the thread above, aside from all the marketing rhetoric, spikes have limited value in an audio set up.  Putting spikes underneath an amplifier is nuts and provides no discernible sonic change.

Isolating a turntable makes sense for obvious reasons. Using spikes versus rubber feet underneath speakers provides questionable benefit. 
 

Isolation pucks can be obtained fairly cheaply for about 40 bucks so not a big deal to do it.

glorified overpriced isolation stuff is generally A waste of money and provides no sonic benefit that's discernible. Positive reinforcement clearly runs rampant in this area.

I’m not debating the quantum level effects of what spikes do. Clearly you can measure anything to death and confuse an issue.

I read the article referred to above and it’s another one of these articles that is incredibly confusing and difficult to follow. At the end it does say ‘isolation is easy to perceive’ so I guess it must be true. It all boils down to this single comment, which really needs a lot more clarification I think in light of everything that was said in this article.

I believe the article does say spikes are pretty senseless.

I am failing to see anyone who has ever really said there are discernible sonic benefits to using isolatIon peripheral equipment.
