IsoTek V5 Polaris 6-Way Power Strip & Filter

The IsoTek V5 Polaris is a filtered 6-way power strip with six individually isolated outlets and an included EVO3 Initium power cable.

Polaris is IsoTek's value-for-money classic: enough connections for a complete stereo or small AV system, each outlet filtered separately so that sources, amplifiers and streamers don't interfere with each other's power supply.

Why the V5 Polaris?

The centrepiece is a Delta filter topology that, according to IsoTek, filters many times the usual standard – over 20 dB of cleaning at 1 kHz, 42 dB at 10 kHz, exactly where high-frequency interference starts to become annoying. The circuit board carries twice the usual amount of copper and is silver-plated, surge protection sits at 45,000 A. Six sockets, six separate paths – no series loop-through.

What you hear

More calm between the notes, a tidier soundstage, less haze over the details. Especially in mixed hi-fi/AV systems, where the power supplies of TV, streamer and amplifier meet, the separate filtering makes the difference.

Who is the V5 Polaris suited for? (and who not – plain talk)

The right choice for a complete system with up to six components. Plain talk: if you run a large power amp with high peak-current demand, you should consider a high-current conditioner like the Titan – the Polaris is rated for 10 A and is more the clean all-rounder than the powerhouse. For most real-world systems, that's exactly the right league.

Our verdict

The V5 Polaris is the sensible standard for clean power distribution across a complete system: six individually filtered outlets, solid protection, cable included. Value for money that's hard to beat. The specialist press agrees: the V5 Polaris carries the ecoustics Editors' Choice Award 2025.

Frequently asked questions

Is a power cable included with the IsoTek V5 Polaris?

Yes. The Polaris comes with an IsoTek EVO3 Initium power cable (1.5 m) in CH or EU version, plus a wall mount. It's ready to use right away; a cable upgrade is optionally possible later.

What does the separate filtering on the V5 Polaris achieve?

Each of the six outlets has its own filter path instead of a series connection. That way, interference from one component doesn't spread to the next – the audible advantage over a simple power strip.
