Grant,I may get an equalizer, if only to use as a design tool. I have listened to a few in the past, but found them to bring other problems with them - like veiling, grain or harshness. I certainly haven't listened to all of them though. Perhaps someone could recommend a good one.
Zip cord is another name for lamp cord, commonly used on appliances. By making a small cut between the two insulated wires and pulling the ends apart, the cord can be unzipped (the two wires can be separated). For a relatively low power, in-home system, zip cord would have adequate power handling. Some people feel that it works very well for speaker cable.
A lot of work has gone into them, but it is a hobby that I really enjoy. At this point, most visitors (including a few 'philes') find the sound to be amongst the best they have heard. I enjoy listening to music through them, but can hear a few defects. So the quest will continue...
