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.
