Hi Barry:

I think you might be right with regard to energy drainage... being a scientist (admittedly a chemist and not an engineer) I have a bit of trouble swallowing some of the claims made by 'tweak' manufacturers.

With regards to the spiked support, I suspect that the mass of the support merely 'tunes' the resonant frequency. If I have a heavy equipment stand (with a low resonant frequency) on which I place a light spiked support (with a high resonant frequency), then I may be able to minimise the transmissions of certain frequencies to and from my equipment.

As an example, if I place my rega planar 3 directlyon the top shelf of my salamander equipment rack, and tap the shelf with a finger, I can hear a low-frequency 'thud' through the loudspeaker. If I put the rega on a light spiked support, and repeat the experiment, the 'thud' is much lower in amplitude, and is higher in frequency.

Best,
JBC
