Your reference to eddy currents reminds me Frank of a traumatic event that I have not been able to explain. I had on loan an amplification chain -Spectral dmc12 and McCormack DNA1- and a pair of MIT330 interconnects. One of the MIT RCAs was defective and I could not use them so I placed them on top of the pre. One day as I was changing a CD I moved my hand over the interconnect. I did not touch it and it was not connected to the sysrem anyway. There was a loud brief ugly sound and two tweeters and a woofer died on the spot. I suspected some kind of magnetic field like when you change the reception of a radio by moving in the room. I have no idea what is inside the famous MIT boxes. Supposedly the dealer spoke with MIT and they repaired my speakers free of charge. However I was never given an explanation. Anyone knows what happened? Sorry for straying from the topic.
Going Topless
When changing tubes on my ARC preamps, I noticed a substantial lift in performance when the top covers were left off the units. An increase in "Air", 3D and just plain "relaxed ease" was appearent when the covers were off.
Now my particular units have Litz signal wire running from input selector and PC board to the RCA I/O jacks in the back. These bundles of wire come close to the top chassis cover, without actually touching it.
Are we dealing with "Eddy Currents" here? I have come to the conclusion that all (music)signal carrying wires, must be isolated from close proximity to metal. I have heard the same effect on ICs and Speaker wire. All of these wires appear to be well shielded and use a stiff dielectric. There must be stray Magnetic Eddy Currents at work here.
Anyone else go through this? Better yet; Can anyone explain this?
The moral, Metal and wire don,t mix...........Frank
