What can we ask of an electrician to ensure good AC power from our home when it comes to our listening rooms, and how important is that power?

Most people aren’t lucky enough to have both a dedicated home theater and 2-channel audio system. So what’s the secret to having both?

Back in the days of Thomas Edison and Nicola Tesla there was a huge debate whether to go AC or DC with our power grid. Paul answers if we should be rethinking this when it comes to our audio systems.

Ground is what is beneath our feet, but what about signals? Does equipment need earth ground? And, if so, how do battery powered units work? Or, 2-prong AC plugs without any 3d wire ground? Paulk answeres these questions and more.

In purist audio realms, the bass and treble controls are often unavailable on equipment and even shunned and despised by audiophiles. Why is that and is there any truth to the notion that tone controls make the sound worse?

Setting up a subwoofer properly brings a wealth of new information to the high end system and fills in where the main speaker leaves off. But, setup can be a challenge. Here’s an easy solution.

Horn loudspeakers are very popular, but are they any good? What is their attraction to audiophiles? Paul gives us the down low on these speakers and explains how they work.

Audio engineers start with a lot of measurements that look at everything from distortion to frequency response. For most companies, that’s where it ends. But for high-end audio companies like PS Audio, it’s only the beginning.

When speaker designers voice their new products do they try and match it to a specific amplifier, like a tube amp? Or another? Or, is there a way they do it in a neutral fashion?

The finest AC power regenerators are built with traditional class AB technology in their output stage, like the PS Audio Power Plants. Why not use an efficient class D amplifier instead?
