The PS Audio Duet Power center is a fairly-priced product that gives you exceptional performance. I came to that conclusion very quickly after using the Duet with several components. No need to make this more complicated than it is. The Duet is simple- a small box that features four outlets in two individually isolated zones, and IEC connector for a high-quality AC cord to connect to your wall outlet.

According to PS Audio, the Duet is the world's first passive component-level AC power center to offer true surge protection and outstanding AC filtering in a small, affordable package. I'm not sure about the world's first, but as far as filtering and protection features go, I agree.

The Duet offers both common mode and differential mode noise filtering of the AC line via Nano Crystalline technology, which PS audio claims provides the highest level of AC filtering of any product in the world. It improves performance of connected equipment and provides a safe and noise reduced power source for both audio and video. Passive A/C cleaning and protection devices purify AC and protects connected equipment.

I love the clever shape of the Duet—not just a square box, but flat on top with 45° angle in the back. You can easily put it on a shelf or a rack, and if you place it on the floor you can either lay it flat, or tuck it between the floor and wall at an angle. Great for those really stiff power cords that can be pesky to attach.

The IsoZones, individually isolated zones meant for different equipment such as analog, digital, or video, are an interesting feature. Don't mix 'n' match!
