Cable Distortion and Dielectric Biasing Debunked

Cable Distortion and Dielectric Biasing Debunked

Recently I've done a collection of measurements and tests on interconnect cables to see what I could find that would explain the sonic differences that many people, including myself, have grown accustomed to hearing. The test equipment was an Audio Precision System 2 Cascade. Test objects were a handful of cables of varying construction and claims to audiophile performance.

This article explains the concept of distortion and whether or not cables can exhibit non linear behavior to produce it.

Calculating Inductance of Zip Cord Speaker Cable

Calculating Inductance of Zip Cord Speaker Cable

A typical Twin Feeder cable, or more popularly referred to as "Zip Cord", consists of two adjacent conductors separated by insulation, or commonly referred to a "dielectric". For convention we assume Conductor 1(+) current flows from left to right, and Conductor 2 (-) return current flows from right to left.

How to calculate Inductance of Zip Cord Speaker Cable and how skin effect changes internal inducatance at various frequencies.

Cross Coax Cables Design vs Zip Cord

Cross Coax Cables Design vs Zip Cord

There seems to be a trend lately for DIY self proclaimed audio gurus to design alternative speaker cable designs using Coax cables (namely Belden 89259). While their efforts should be applauded, they should also be cautioned to consider any deleterious effects that may result, while also objectively analyzing their designs against conventional and proven twin feeder ones (ie. 12AWG Zip Cord) to determine if the design characteristics (namely DC Resistance, Inductance, and Capacitance) are at least equal to justify their design efforts.

Skin Effect Interview with Dr. Howard Johnson

Skin Effect Interview with Dr. Howard Johnson

Although this may seem to be a trivial matter to you, many audio cable vendors and forum cults enjoy spreading fallacies about skin effect and "strand jumping" on speaker cables and interconnects. I am attempting to disprove the relevance of Skin Effect at audio frequencies and the fallacy of "strand jumping" for this application.

Skin Effect Relevance in Speaker Cables

Skin Effect Relevance in Speaker Cables

Some so called "exotic" Cable Companies enjoy spreading the fallacy that Skin Effect can cause deleterious effects on your audio performance. While Skin Effect is a real world problem in high frequency applications such as RF Power and Transmission, it is negligible at audio frequencies as I will demonstrate in this article based on fundamental engineering and scientific principles.

Skin Effect is a real problem in high frequency E&M; transmission but does it matter in speaker cables at audio frequencies? This article explores that very topic.

Top Ten Signs an Audio Cable Vendor is Selling You Snake Oil

Top Ten Signs an Audio Cable Vendor is Selling You Snake Oil

The markup on cables is extreme. There are some good companies out there, but there is also a lot of snake oil and scam artists. We give you the top ten list (plus some bonuses) of what to watch out for when shopping for AV cables.

this is a top 10 list of snake oil scams often seen with consumer audio speaker and interconnect cables. Audiophiles be warned.

Component Video Cables - The Definitive Guide

Component Video Cables - The Definitive Guide

Component video cables are a key interconnect element to any Home Theater System. To better understand how these 75-ohm cables can affect a video signal from a DVD player, it is helpful to cover some fundamental engineering principles that define them. To begin with, the primary purpose for 75-ohm component video cables is to conduct an AC video signal from a source (DVD player) to a load (TV monitor) with as little change to that signal as possible.
