Chang Lightspeed power filters

Chang Lightspeed power filters significantly reduce AC mains contaminants and impurities while protecting your equipment from potentially damaging voltage surges.

New models introduced in 2023 provide a range of outlet types (digital, analog source, analog maplifier) more suited to today's mix of digital and analog components. The new Reference mk5 has no fewer than 14 outlets to cover all your audio, video and gaming needs.

Using proprietary magnetic core materials that are now in their 3rd and 4th generation, these no-nonsense designs offer effective power filtration without compromising power delivery unlike isolation transformer based designs which limit current delivery once the transformer core has become saturated.

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). Movies and games have never looked better!

Made by a small family-run company in the USA for over thirty years, these hand-built 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.

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.

Be sure to get the latest versions and competitive pricing by ordering from kemela.

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