Monster Cables MP-AV600 uses the traditional power strip design, lining all of its six AC outlets up in a row. Though the form factor is traditional, the coloring of the MP-AV600 is not. Monster color codes the outlets and even includes labels so you can easily disassemble and reassemble your system. In addition to suppressing surges, the MP-AV600 filters electro-magnetic and radio-frequency interference (EMI/RFI), which the company says has been known to produce hums and buzzes in audio equipment. One of the best features of this suppressor is the 360-degree swiveling, right-angle plug with 24K gold contacts. The right-angle plug lets you place furniture close to the outlet, while the gold contacts will not easily corrode and dirty the connection. Surge suppression is measured in joules. This surge suppressor carries a joule rating of 420.
