By now, it should have become common knowledge that operating a standard power strip will most certainly save the music lover from the maximum in sound quality. There are a number of plausible reasons for this. For one thing, one must be aware that the hi-fi system is of course not only connected to the wall socket, but is also influenced by all other devices in one's own home and also those of one's neighbour. Electromagnetic interference, which can be caused by refrigerators, hoovers, computers or LED lamps, finds its way unhindered into the music system. In addition, all cables have the effect of an antenna - but the RF interference caught in this way definitely has no place in the hi-fi chain. To make matters worse, the components also have the potential to interfere with each other. Another requirement that effective power supplies must fulfil is the protection of the connected devices against overvoltage. Last but not least, the mains distribution should offer as little resistance as possible to pulse-like energy consumption.

In the meantime, there are many different power supply concepts on the market, whose technical approaches certainly differ. However, it does not seem sensible to us to ignore even one of the above-mentioned aspects. After all, if you are going to take care of supplying your hi-fi or home cinema system with a reasonable amount of power, all possibilities of negatively influencing the sound quality should be excluded. IsoTek is one of the world's leading suppliers of such solutions. With the six-way distributor V5 Sirius, the Englishmen now offer another concept that has been thought through to the end and, above all, is affordable. The bar, which weighs a good 1.9 kilograms, is presented in bright silver. On the front side is the C19 power socket, to which the EVO3 premium mains cable, which is part of the overall package, is connected. On the opposite side, the central mains switch and a »System Link« socket are mounted, to which further IsoTek mains distributors can be connected if necessary.

On the top are the six solid sockets, each individually wired, and a bright white LED indicator that signals operation. There is no phase identification. This must therefore be found out and marked with the help of a phase tester, because the phase-correct connection of the components is always a prerequisite for a really above-average result, since the output currents flowing through the signal cables are lowest in this case. Between the Sirius cold device socket and the slots, the current passes through various filter stages. First, the mains noise is suppressed, and for this purpose high-frequency interference is effectively filtered and converted into heat. The common-mode noise is reduced by means of choke coils. There is no mutual interference between the components because each output is wired individually.
