Introduction The ExactPower EP15A is a power component designed to regulate and improve the quality of the AC power that is supplied to your audio/video electronics.

Introduction Power-related products are gaining greater acceptance as more AV enthusiasts are realizing the benefits of cleaner power delivery and the negative effects it has on audio and video playback. This is a field that has had its history tied to high-end audio for years, where the benefits have been known to make substantial improvements to detail, depth of soundstage and low noise floors.

Introduction One of my criticisms of AudioRevolution.com -- and nearly every other AV publication for that matter -- is the fact that every time a new issue comes out, there are hardly ever any write-ups on affordable components. While we are raving about $16,000 AV preamps and $24,000 speakers as if they are the Second Coming, it can be easy to forget that not everyone goes to the stereo store every month to get a five-figure AV fix. But we all are junkies to some extent, aren’t we? This is why we are always looking for a great-sounding CD or a DVD that looks amazing because it was transferred from 70 millimeter film – right? That is the fun of owning a great AV system. Well, I have found a good upgrade for those who are looking to mainline a little audio-video ...

Introduction A friend once said to me, "I have several known problems with my audio system, and you are suggesting that I fix one that I didn’t even know I have?" He had a good point except for the fact that sometimes you need to get rid of a problem to appreciate that you ever had one. So, who has these power problems and for that matter, what the heck is a power problem? What does your power have to do with the quality of your sound? First of all, just about every audio system suffers from poor power. The power to your home runs through power lines that are shared by many others. Each home is most often connected to a power transformer that is shared with at least several houses. When these houses use appliances, noise is transmitted through your ...
