IsoTek EVO3 Isoplug

The IsoTek EVO3 Isoplug is the simplest way to cleaner power: a parallel mains filter that you simply plug into a free socket on the same strip – no inline connection, no power loss.

Rather than sitting in the signal path, the Isoplug works in parallel: it doesn't divert anything or limit any current, but simply reduces high-frequency mains noise "on the side" – right where it's plugged in.

Why the EVO3 Isoplug?

Because it's the cheapest and simplest entry into IsoTek's power cleaning. No re-plugging of devices, no extra cable – a free socket is enough. Especially handy for upgrading a simple power strip.

What you hear

Depending on mains quality, sometimes more noticeable, sometimes subtler: a bit more calm in the sound, a slightly blacker background. A small but honest effect at a small price.

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

For an affordable entry point or as an addition to a simple strip. Plain talk: it doesn't replace a serious power conditioner like the Aquarius or Sigmas, but complements the system in places where otherwise nothing would be filtered at all.

Our verdict

The smallest, most affordable step towards cleaner power: plug it in, done. No substitute for a conditioner, but an honest effect at a modest price.
