This cannot be answered definitively. Sometimes the Cardas blox or Racing Cones may be better than the other, but sometimes not. Each will change the sound somewhat, and you must determine which you like better. I had the Cardas blox under my preamp, I switched power cords, and they didn't work well for that configurtion. I got my preamp updated and the Cardas blox went back into their position under the preamp again. There are many of these kinds of devices..each has their place..could be in a drawer. You must listen and decide for yourself.
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.
