Where to use Isolation devices


Do isolation devices work on all components? I have a cd player, tube amp(Herbie's tube dampeners on all tubes) and preamp. All components are on a dedicated stand with at least some reasonable dampening. I have the cd player under some myrtle wood blocks, and nothing under the amp and preamp...I was thinking maybe something like the Black Diamond Racing cones I have heard so much about, or something similar.
Thanks

With your indulgence, a rant:
If I walk into a familiar room, full of knickknacks, I’m much more likely to notice a newly acquired knickknack, than I am to notice the removal of one. That’s because, over time, we all become consciously blind to details that are very familiar to us; or at least, we lose some awareness. Okay, where am I going with this? There is no element of audio that I find more agonizing than the struggle with isolation devices. Chief among woes, is that there is usually a give and take factor; and I notice what they add to the music long before I notice what was subtracted. Here’s the rub: since I can find no science to help me determine their proper usage - not to mention the outrages prices and snake-oil factor - I feel trapped. If I don’t use them, then what am I missing? And if I do use them, then what am I missing? Thank you for your indulgence.
