IsoTek NEW V5 SIRIUS is said to be better than ever before

The new V5 Sirius is an ultra-high performance power bar, harnessing IsoTek latest mains power cleaning technology, which both protects and improves your audio systems performance. If more power output sockets are required, a unique IsoTek ‘System Link’ connector is provided, allowing users to connect multiple IsoTek units together whilst maintaining star-earth. In addition, a special wall bracket system is provided, which enables users to mount the V5 Sirius discretely behind their audio system.


The existing EVO3 Sirius is a compact yet elegant power cleaning and distribution bar measuring 555mm in length, 88mm wide and just 55mm high. It features six independent outlets, each one referencing back to the central PCB to dramatically reduce Differential Mode cross contamination of connected components. Most power filters of this style join output sockets together, running each in series. This has a negative effect on sound quality, as Differential Mode Noise created by the connected electronics will cross contaminate from one output socket to the next. The superior electrical architecture and design of Sirius eradicates this, ensuring the very best power performance to all connected devices.

The new V5 Sirius features a unique high grade and high amperage choke system combined with high frequency delta filters, ensuring class-leading power cleaning of both Common Mode and Differential Mode mains noise across a wide frequency range. This is combined with IsoTek’s unique Inductive Resonance Gate ©, which further optimises the isolation between each of the six output sockets. Clean power is then delivered to all six output sockets – each one independently isolated to prevent cross-contamination of mains noise. KERP © (Kirchoff’s Equal Resistance Path) ensures equal resistance and equal power delivery to all outlets.

The internal wiring is unique and specifically designed to offer the highest standards, utilising pure 6n oxygen free copper conductor strands with silver-plating to offer low resistance and high amperage. An FEP dielectric is then used to protect the conductors as well as giving the ultimate low resistance power delivery system.

Furthermore, a 54’000 Amp instantaneous yet transient protection system enhances sound as well as protecting precious audio components from dangerous power surges and voltage spikes. This unique safeguarding system features IsoTek’s sequential cascading VDR protection method, which offers superior safety without dynamic audio or sound restrictions.


The V5 resettable fusing system offers a substantial upgrade over a standard ordinary fuse, due to the increased contact area. By shear virtue of its electrical function, a standard fuse must have a very thin wire, this being also true of expensive audiophile grade gold plated versions.

The internal wiring of IsoTek products synergises with the range of IsoTek power cables. One critical but overlooked area is maintaining commonality of design and material properties though an audio wiring loom, be it signal carrying cables or the power cable network.

Housed in an extruded aluminium chassis, Sirius is a solid, hard-wearing power bar that can easily be wall mounted behind audio systems or placed discretely behind audio racks. Sirius is supplied with IsoTek’s multi award-winning Premier power cable.
