In the Thread: We who are about to die... (a cable thread)
Post Subject: Multi wire hellPosted by Bud on: 6/29/2008
Romy does explain things correctly, in his own way of course.
Modern electrical field theory has it that the electrical field attached to a cable, stops progressing along the cable for every vector change in the field. Not exactly a digital event but close. Once the vector change has followed the information packet demands, the electrostatic field collapses into the B field, or what is called current. This continues until the next vector change and only occurs for "AC signals"..
During every vector change, the field, which has a vast gradient of differing charge values, must reach out and affect a change in the charge on the end of a near dielectric dipole. Many trillions of these at once. These dielectric dipole charge ends are typically found in plastics, surrounding the field event carrier, known as "cable".
These plastics have a charge rate vs charge level, over time, and if it is not fast enough to fully support the field event, then lower charge portions of the field event will be lost to the information packet.These become random, charged fields of their own, called noise.
The B Field event, when the E Field event collapses, is not affected by anything but another EMF field, intersecting the cable it is attached to. The E Field event is therefore the malleable event in a cable.
The only reason to use Litz wire in a cable is to obtain enough surface area that a small amount of dielectric can be used to "tune" the E Field characteristics. Also keep in mind that, in the entire signal chain, for one information packet thread, there will only be one static moment and it will take the entire length of the chain to express into and be supported. So, cables and their losses are only part of the problem.
Lack of proper grounds within electrical equipment are just as, if not more important problems, than anything cable might provide. Most modern circuit design has no effective mirror ground plane. You might look at Romy's last phono corrector build, to see what is a correct ground plane implementation. Your digital source has nothing like this and thus, all of the sharp sound and thin values of red book audio are really just information that has been dropped, right at the "line stage" output on the end of the DAC. Red book audio is actually a very good signal source, when the information packet created in the DAC is maintained through the entire signal chain, through proper grounds and proper cable dielectrics.
