Coherence Systems ADD-POWR Wizard

Further Information: 

Coherence Systems is owned by the guy that sold the qcoil technology to Nordost. The Add Powr stuff has similar devices in the range to the Nordost offerings but have improvements in the implementation of the concept. The Wizard is similar conceptually to the Nordost QX4 power purifiers. The explanation is that it adds low frequency square waves to the mains waveform.

I have no idea what mechanism is at play but the Wizard has a pretty immediate effect once you switch it on. There are quite a few owners and reviewers that have described the improvements very accurately, however, ultimately, the best way I can sum up the effects of the unit are that it makes music much more enjoyable, engaging and helps you understand the emotional content of the music.

The Add Powr also seems to be able to "spread" its effects across your mains network. I can attach it to a different circuit and still hear its effects, though not as powerfully as when it is on the same circuit as my stereo setup.

I have confirmed with the manufacturer that the unit is set to 230V operation.

These guys seem to have nailed it -
