Dielectric Absorption in Cables Debunked

Dielectric Absorption in Cables Debunked

Before we debate the relevancy of Dielectric Absorption relating to speaker cables, and commonly perpetuated by many exotic cable vendors and cable cult hobbyists, let us first define the roll of a dielectric. Can an insulator really affect the sound quality of a speaker cable and can it exhibit characteristics of a capacitor dielectric as some cable vendors claim? Read on to find out.

This article explores the claim by some cable vendors that cables exhibit dielectric absorption like a capacitor. We discuss the purpose of a cable dielecric and whether it can affect sound.

A Practical HDMI Cable Solution & Installation

A Practical HDMI Cable Solution & Installation

Every house I've ever purchased, built and lived in all had one thing in common. A room built for Home Theater. Regretfully I had to sacrifice that in this house and after a long debate with my wonderful wife, I had her agree to allow me to have a Home Theater System in our one and only living room. But there was a huge contingency attached to this contract. She did not want to see any wires. We'll, everyone knows the impossibility of this monumental task.

HDMI Fiber Optics & Copper Cable Considerations

HDMI Fiber Optics & Copper Cable Considerations

When it comes to HDMI / DVI connectivity, you have two choices: Copper or Fiber Optics. Which is right for you? As digital displays become more popular, and more people understand that a DVI or HDMI "pure digital" connection delivers the best HD picture quality available today, the decision of which type of cable to use is challenging and requires thoughtful consideration.

APC Interview on Power Conditioner Devices

APC Interview on Power Conditioner Devices

Over the past few years we have put forth our best effort to demystify the industry on cable snake oils and ficticious claims. While this battle isn't quite yet over, we are happy with the progress that is being made to educate consumers on sound engineering concepts about these products.

Balanced vs. Unbalanced Cables

Balanced vs. Unbalanced Cables

This article is a primer for discussing the differences and applications for balanced vs unbalanced cables. When using unbalanced interconnections between audio equipment the primary noise-coupling mechanism is due to common-impedance coupling. We discuss noise methods of eliminating this as well as common causes of such phenomenon.

Balanced vs Unbalanced interconnects and cables, what is the difference? This article discusses both cable types and gives you the pros and cons of each. Use balanced cables whenever you can.

Video Cables from the Inside Out

Video Cables from the Inside Out

When reading descriptions of home theater cable products off of packages in a big-box store, or off of websites online, it's sometimes hard to get a clear understanding of just what, exactly, is inside a length of cable. It often isn't clear where the engineering-speak ends and where the marketing-speak begins, and the marketing-speak certainly isn't usually designed to aid understanding.

Understanding In-wall Speaker, Video and Audio Cable Ratings

Understanding In-wall Speaker, Video and Audio Cable Ratings

We're often asked questions about the suitability of particular cables or speaker wires for in-wall installation, and it's not surprising; with surround speakers being wired all around home theater rooms, ceiling-mounted projectors being located across the room from their video sources, and video and audio being distributed all over the home, it's natural that people want a clean installation.

Understanding Digital Interconnects

Understanding Digital Interconnects

Keeping a signal in the digital domain until the very last instant before it is converted into the compressions and rarefactions that are sound - or the illumination of pixels or scanning lines that are images - is generally considered the best platform available to the contemporary audiophile. Regardless of the signal's origin we can all agree that multiple trips through analog-to-digital and digital-to-analog converters cannot do anything positive for the listening or viewing experience.

Video Cable Shielding

Video Cable Shielding

All common video signal types--composite, RF, s-video, component, SDI, and the various flavors of RGB--are ordinarily run in coaxial cables, or, as the shorthand term goes, "coax." The features of coax which make it ideal for handling these multiple signal types are its excellent impedance tolerance and its shielding; here, we'll discuss what shielding is, why it's needed, and what the best types of shields for video cable are.

The Truth About Interconnects and Cables

The Truth About Interconnects and Cables

I refuse to prove that my cables will make your system sound better", says the snake oil vendor, "for proof denies faith, and without faith, you will hear nothing. This editorial discusses the crazy cable myths that float around and how audiophiles often fall prey to them. We recently added a satire YouTube video discussion on how the price of cables affects sound quality.

This editorial gives you the truth about audio interconnect and speaker cables and wires and debunks the myths that often surround them.

Signal and Connector Types for TV and HDTV

Signal and Connector Types for TV and HDTV

There was a time, not so long ago, when television hookups were pretty simple. There were two screws on the back of the set, which went to two spade lugs on a 300-ohm twinlead antenna line, and that was it. Apart from plugging the set into the wall and waiting for the tubes to light up, there wasn't a whole lot else to know about connections. Today, things are a bit more complex as far as the digital age goes for television and HDTV.

The article discusses the various signal and connection types for television and HDTV from composite cable to HDMI and more.

Exotic Materials and Audio Cable Construction

Exotic Materials and Audio Cable Construction

A lot of discussion of quality cables focuses on the materials used in audio cable construction. Just as with any physical product, the materials cables are made out of influence their performance characteristics, and so people want to know that the cables they're buying are made from the best possible materials. Are silver cables really better than copper? We answer that with our recently added YouTube video.

Exotic audio cables often use fancy materials such as silver wire or teflon dielectrics. But do these materials really translate to a performance difference? Read the article and watch our Youtube.
