I put in a dedicated circuits -- 2 20 amp lines for my audio system that features three amps: 100 w tube amp, 400 w ss amp and a 1200w ss sub amp. I run the tube amp (high current) and all the front end equipment through Panamax 5100 on one circuit and the 2 ss amps through Triplite surge suppressor on the other. You can do this yourself if you are handy or hire an electrition like I did. It cost me about half as much as Panamax 5100. It was definitely one of the better buys.
