Bob......some corrections to your statement.
I don't know where Mr. Brisson obtained his information, but the Cable Cooker does NOT put out *any* DC component in its multiplex signal. Period. The Cooker puts out a high-voltage, high-current, steady-state signal in addition to a swept square wave covering the audio band.
It may be that the capacitors in the MIT boxes are shorting the Cable Cooker at higher frequencies, causing the Cooker's power supply to immediately shut off. This is a built-in safety feature of the power supply. If it sees something it doesn't like (like a current or voltage aberration), it shuts off. Also, there would be NO damage whatsoever to the cabling.
Two Cooker customers had this occur to their MIT cabling. The LED's on the Cooker "blinked", as the unit simply didn't operate. They reinstalled the cabling into their systems and everything worked just fine. Unfortunately, no further conditioning could take place. Owners of Transparent cabling have no problem with the Cooker, nor does the Cooker have any problem conditioning Transparent Audio cabling. The LCR networks seem to benefit from Cooking, as do the cables.
