Mains Cables - Puritan Audio
High quality mains cables are designed to isolate your equipment from RFI (radio frequency interference) and are usually made using much higher quality materials. The question of whether a mains cable has a positive effect on sound and picture quality used to be a hotly contested topic, but it's now widely accepted that a good quality mains cable is a worthwhile investment to reduce interferences. For the best improvements, we recommend also using a high quality mains block.
Using a high quality power cable is the last link in the chain to connect your hi-fi system, and a shielded cable will protect the power supply from EMF noise and RFI (radio frequency interference).
Good quality mains cables and interconnects are some of the most effective and best value upgrades you can make for your listening pleasure. If you've already made a good investment on the system, don't you owe it to yourself to give it the cables it deserves to hear how good it can sound? Don't forget to use high quality mains cables with a suitable mains filter or mains block.
Puritan Audio make a range of mains cables and power distribution bricks designed to remove noise from the mans supply before power reaches your sensitive audio equipment, along with surge protection. The Puritan range spans from the entry level Guardian to the ultimate level studio Master series.
Guardian level: The entry level products still feature all of the expertise that make Puritan products so popular. They have a heavy steel case that shields the components, as well as output filtering and surge protection. Entry level units have four outputs and 20 levels of filtering. There is also a model with DC removal.
Intermediate level: A step up are the Puritan power strips, these have more outputs. The casing is of heavier gauge steel and the six outputs can handle 15 Amps each. There is also 23 levels of filtering, as well as enhanced differential and common mode noise removal. DC removal is also optional.
Master level: The master level series consists of three models, starting with the PSM 136. These units have progressively more filter levels with the PSM136 having 39. All the master units have DC removal , there is also a 12 output version. Another difference is the individual output filtering . This prevents cross contamination.
The flagship model is the PSM156. This has 58 filter elements . Moreover, Each filter section is doubled in efficiency and there is a 12 outlet version of this model, available. The wiring is made of oxygen free copper. Finally, the mains sinewave is rebalanced to prevent any DC from interfering with the efficiency of toroidal transformers, as used in amplifiers.
Mains cables: Puritan audio also make high-end power cables. Poor cabling can undo all of the work done by mains purifiers. Puritan mains leads use unique materials technologies, to reduce noise pickup. Unshielded cables can act as an aerial pulling in all kinds of interference. Moreover, conventional shielded cables just dump any interference into the earth system. However, Puritan cables use dissipative technology to convert the received interference into heat. This prevents the earth system from being saturated with noise.
