How important are spikes?

I’d have to imagine rubber feet produce a different sound than spikes and each has their uses, and then there’s always personal taste. I always thought these Gliders from Herbie’s were a neat alternative to spikes as they allow for easy movement and also provide some meaningful isolation, and users give them high marks for both convenience and sonic improvements. That they’re relatively cheap is an added bonus.

How important? Very little importance…. 

Speakers a little different. Rack of electronics. Not so much. If worried about it buy some decoupling pucks to put under your components. 

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.

@emergingsoul There’s not one thing you said that I agree with.  Not one.
