and yet at the same time allows any vibration in the amplifier chassis to be 
“sunk” to ground. 
 

The function of the steel spike is to have a low-impedance point to transfer 

all frequencies to ground. This is possible because the contact at the point of 

the spike is smaller than a ½ wavelength of the frequencies of vibration 

transmitted. Using a steel cup under the spike will defeat this function and as 

this will only allow passing frequencies have a ½ wavelength larger than the 

diameter of the steel cup, which is far larger than the point of the spike. 

 

Hence, if the amplifier is to be placed on a hardwood floor, and you do not 

want to mark the floor, use a thin disc of copper (a copper penny will do) 

under each spike. The weight of the amplifier on the spike will deform the 

disc and create a small indentation. The other side of the indentation will 

form a little nipple to couple to the hardwood floor. Alternatively, use a little 

square of aluminum foil that is at least 4 layers thick. 

 

Other features that have been incorporated include: 

 

All signal wiring user silver strands with a copper core and PTFE 

dielectric.  

 

Having all critical components toleranced and matched to less than 

+/- 1% results in a sense of aliveness and ease in the music. 

 

Special circuitry to “keep things warm” without wasting a lot of 
electricity means that your system is ready for you to listen to 

whenever you are. 

 

High-power, high current relays to switch power instead of typical 

rocker or toggle switches result in minimal degradation of the power 

supply path.
