Black Noise Mains Filter Extreme. Made in Italy. $820 MSRP

This is one of the better power conditioner that focuses on eliminating or reducing the EMI/RFI interference in addition to its surge protection features. Designed for EMI/RFI sensitive components like CD players and preamps, the Extreme offers two dedicated outlets for these devices in a solidly made aluminum casing. Maximum power draw is 230W. Cosmetically, the unit looks fair with the usual scuff marks/nicks from use but nothing major. Unit will be securely packed for safe shipping.
