Emotiva CMX-2

Emotiva calls this product a "Precision AC Line Restoration & Common Mode Filter System”. Their website says "The CMX-2 offers a solution to a less-familiar, common problem – DC offset on the AC power line. DC offset is usually the result of unbalanced loads or by flaws in the power distribution system itself. It can cause DC current flow in the transformers that power your audio equipment, making them run hotter, produce more mechanical hum, and, in extreme cases, even potentially causing permanent damage. In addition to removing line noise, the CMX-2 also totally eliminates this annoying and potentially damaging problem as well." This is a current product. There is more information about it on the Emotiva web site. Included are a 7 foot 14 AWG IEC power cord and screws for mounting the unit vertically.
