Maximise your entertainment

Without mains power, no audio or audio-visual component can function. Your musical enjoyment is reduced by mains noise contamination – this can be from either Differential or Common Mode mains noise. Differential noise is created by the power supplies in all electronic devices, while Common Mode noise in introduced by RFI and the wireless communications that are becoming increasingly common. With the Performance range you will hear significantly better sound quality, with more detail and greater dynamic range. All of your components will be improved and protected, allowing you to realise the best possible performance whenever you listen.

The IsoTek EVO3 Sirius is a power bar with a central filter network which removes both Differential mode and Common mode noise up to 40dB. Each of the six output sockets references back to the central filter network, thus Differential mode noise cross contamination is dramatically reduced.

All electrical products that draw power from the mains supply create Differential mode noise, including audio components. Connecting outlets in series with big copper bus bars enhances cross contamination of Differential mode noise which is not ideal for high quality audio replay.

Sirius also offers 22,500A of instantaneous protection against dangerous power surges and voltage spikes.

Housed in an extruded aluminium chassis, Sirius is a solid hard wearing power bar that can be wall mounted behind audio systems or placed discretely behind audio racks.

“For the characteristics that Sirius brings to the party, it is a conditioner that will really appeal to jazz, classical and acoustic music.  It’s one of those devices that once you take it out of your Hifi playing this type of music, you probably won’t want to go back to how things were before.” 13th Note – October 2019  Full Review

“Excellent value for money… A great real-world product that is useful and inexpensively upgrades your system”
