My apologies to all. It seems that I have missed all the fun.
It seems that we've strayed far afield from a straightforward end-user experience with an obvious attempt to tie the experience to measurement and science. You've already stated your disdain for the recommended burn-in and use of our cables. As i said before this is your right to do but it obviously influenced the outcome. What you don't have the right to do is claim to be accurately conducting scientific measurements while having a total disregard for proper testing methodology. This is what can happen when a lay person gets their hands on a measurement device and doesn't understand that basic principles of operation nor of proper interpretation of results. Magnetic fields and electric fields cannot be accurately measured when there are many other cables and electronic components in and around the test environment. Further, the measurements are completely invalid when you introduce an in-line filter of unknown characteristics in series with the cable under test. And last - ALL POWER CORDS - radiate electromagnetic fields. The field has a direct correlation to the amount of curent flowing through the cable and of the cable's impedance to current flow. So a power cord that has more current load (like the cable feeding the power conditioner) will have a larger field. Anacondas and other XiTron power cords have stronger electromagnetic fields (not electric fields) because they have less impedance to current flow. An elecrromagnetic field is composed of two fields, the E field and the H field. When there is current flow through a conductor there will be an electromagnetic field generated. The magnetic vector and the electric vectors are intertwined. So, a reading of just one or the other cannot give the total accurate measure of the EM field. At low frequencies, the E field and H field vectors are so widely separated that two separate readings must be taken at precise locations and then summed together to calculate the total field. This cannot be done with a haphazard approach that you have taken. Shielding in power cords is only effective at frequncies far beyond power line frequencies. Most power cords are unshielded for this reason. No power cord that comes in the box with an audio component is shielded. Also you may want to read the Tri-Field manual about the proper procedure for measuring electric fields. --- An electric field that changes with time, such as due to the motion of charged particles producing the field, influences the local magnetic field. That is, the electric and magnetic fields are not separate phenomena; what one observer perceives as an electric field, another observer in a different frame of reference perceives as a mixture of electric and magnetic fields. For this reason, one speaks of "electromagnetism" or "electromagnetic fields". In quantum electrodynamics, disturbances in the electromagnetic fields are called photons, and the energy of photons is quantized. --- A person holding an electric-field meter would perturb the field. To measure the unperturbed field, the meter is usually suspended at the end of a long non-conductive horizontal rod or vertical tripod. The reading is read from a distance on a suitably sized display, recorded within the meter for later analysis, or transmitted to a readout device by fibre-optic. This can reduce perturbation to acceptable levels. However, given the ease of perturbation of electric fields, it is easy to make erroneous measurements, particularly when there is: extremes of temperature and humidity; insufficient distance of the probe from the investigator; instability in meter position; loss of non-conductive properties of the supporting platform. --- And last but not least, if a power cord's electromagnetic field did have any deliterious effect on a system it would manifest itself as a hum in the system. I believe that you said your system was absolutely silent. There has been and continues to be a common theme among users of our power cords. They consistently report an obvious decrease in perceived noise levels and an increase in macro and micro dynamics. This is just as true with tube electronics as it is with solid state gear.

Good post. Interesting information regarding the issues in trying to get accurate measurements. On another forum I read, every once in a while somebody shows up who took a class, learned the DC application of Ohm's Law, has a multimeter, and claims this proves wire is wire, and high-end cables are a fraud. Personally, I enjoy those threads for the amusement potential.
Anyway, thanks again for sharing knowledge and experience with us.

And, not only that, he drives race cars!

Wow! I didn't know that. Fast and furious + the best cables. Nice. Just finished listening to Vivaldi on Reference Recordings through an all Anaconda signal/speaker cable set up I have they includes all King Cobra CX Pc's in my system. The ambient data retrieved is astounding and intensely musical. Just lovely.
