Heres my email correspondence with Victor Tiscareno - VP of engineering at AudioPrism, so far
ME:
Hello,
I'm under the impression that this product will help filter out noise interferences suck as EMI and RF much better than simple use of ferrites. Am I correct in this assumption?
VICTOR:
Yes, the WaveGuide performs the same function as a ferrite bead, except that it works in a lower and broader frequency range. It works well around almost any cable or wire. Power cords and digital interconnects are obvious uses.
ME:
Does it matter where the WaveGuide is installed on the cable or how many there are on the cable?
VICTOR:
It all depends on what you are trying to achieve. If you are asking about noise attenuation, theoretically, more inductance should provide more shielding. If you are referring to improving sound quality, adding 2 WG to a power cord, especially on a power cord feeding a large power amplifier, the better. However, there will be a point where adding more WG does not add anything to sound quality vs cost. You will likely hear changes in sound by sliding the WG along the cable, but I find that installing at either the wall side or as close as you can to the equipment's AC entrance will be best. I ask that experiment fully to maximize the sonic benefits.
If you are noticeably experiencing RFI or EMI through your speakers, the noise may or may not be coming in through the power cable. Believe me, there is always noise on the AC, but what people sometimes think is causing the radio to play through the speakers, may be filtering through the poor shielding of interconnects or skin effect on the enclosure. In other words,
bypassing the power cords with or without WG's installed.

Needless to say, using these things in quantity could get expensive!!
