Isolation Shelves

I know this question has been asked before because I've read the posts concerning two Sistrum vs Neuance.

First let me explain where I'm planning to put my source component in this case a JoLida 100a. For ventilation purposes I'm planning to put the player ontop of my AV Rack which is a Synergy S40 from Salamader Designs. The Top of the unit is made out of solid wood not MDF. I've ordered and expect anyday to recieve my Black Diamond Racing Cones MK4 for tube componets.

Here's my question if I deciede to continue tweaking should I get the corresponding pucks from BDR. This I was told by the dealer is a cheap alternative to the shelve or should I try one of the above mentioned shelves.


Cheers and Many Thanks
