Joncourage, I'm not an electrical engineer either, but I hear the sonic improvements. My understanding of the situation is that in any interface of materials (same or not) there will be some resistance that will create some amount of interference in the electrical signal, often a spike of energy in the very high frequency range. The contact enhancers improve the conductivity at those interfaces, reducing the interference and the energy spiking. The Walker Audio Extreme SST is very effective in my system at improving the sound quality and is sonically the best contact enhancer I've tried. I consider it a necessary component here and I encourage you to give it a try. If it doesn't work for you, return the unused portion to Walker Audio within 30 days for a full refund, less shipping.
