Counter Attack! – The Platform Principle


So how are we going to deal with these problems?  Well, first we’re actually going to talk about the LeadingEdge support platforms. At Vertex AQ we used to make the Kinabalu support platform, but we have moved manufacture of that across to our sister brand LeadingEdge. But LeadingEdge is an integral part of our overall Systematic Approach – and the support platform is a critical element. We’ll come onto RFI and mains conditioning a little later.

Lets start with our supports, because the basic theories here are fundamentally the same in all the other products. The LeadingEdge supports comprise an acoustically ‘absorptive’ platform, a coupling tripod and a further 2 supporting feet (to keep things level). And on the underside of the platform are stop-choc decoupling feet. The tripod is specifically designed to be a low acoustic impedance, and when correctly set up, the arrangement allows damaging acoustics to flow out of the box being supported, down through the tripod and into the platform. How? Well the tripod is a ‘fast’ steel object, directly supporting the ‘fast’ metal casework of the player, and its sat on a steel insert in the surface of the platform – minimum impedance mismatches, maximum transfer!

Its a case of taking the acoustic energy away from somewhere you don’t want it (the electronics) and dumping it somewhere else, where it can’t do any harm (into the platform). 

Note that we use the word absorption to give an indication that the vibration is taken out of the system, but in reality the absorption mechanism is a labyrinth and the vibration is actually ‘nulled’ by destructive interference.

The stop-choc feet underneath the platform prevent any vibration in the shelf or rack from passing up into the platform and player. Hopefully you are beginning to get the idea with these diagrams now. If you see red in contact with red, you know its a good acoustic path, and if you see red in contact with yellow its a bad acoustic path. Note in this example we have shown the player’s own feet as yellow – most manufacturers fit plastic feet with rubber and/or felt parts. The problem with this, as you can now see, is that vibration within the player is left there if you just stand the player on its own feet.

So if we now introduce 2 LeadinEdge platforms into our system, this is what it looks like schematically.

So now we have provided 2 efficient drain routes to take a lot of acoustic energy out of the CD player and amp. If you have not yet had a demonstration of just how much this purely physical action improves performance, we suggest you hear it as soon as you can – it really is a revelation.
