Using proprietary magnetic core materials that are now in their 3rd and 4th generation, highly effective power filtration is achieved without compromising power delivery unlike conventional transformer based designed which can introduce significant time delays that can muddy the sound.
Typical sonic benefits using Chang Lightspeed power filters are lowering of the noise floor, better low level resolution, superior dynamics, and increased spaciousness.
For video, lower noise translates into deeper black levels, increased shadow detail and a finer color palate (more film-like and less pumped-up or blooming).
These solidly made in the USA power filters offer good performance and a generous number of outlets. Chang Lightspeed power filters are a good choice for home theater applications. Even the basic entry level model offers a significant improvement at an affordable price.
Surge protection is easy to overlook but important insurance against damage to expensive systems which can be "fried" in a second. In the event of a powerful surge that is absorbed by the unit, Chang provides the back-up service at modest cost and fast turn around to repair the unit back to full protection ready for the next time and in this regard Chang differentiates itself from many others. By servicing and testing the unit you can be sure that it continues to provide protection. Other units may claim to offer repeat protection but it may not be at 100%.
All Chang Lightspeed power filters are hand assembled and individually tested at the Sylvania Ohio factory.
A mains-in attached power cable comes as standard but upgrades and custom lengths, or a socket for detachable power cables can also be ordered.

kemela does not recommend buying used power filters as the surge protection components may be blown even though the unit appears to be working.
