IsoTek V5 Titan High-Current Mains Filter (3×16 A)

The IsoTek V5 Titan is a high-current mains conditioner with three 16 A outlets that supply powerful power amps with clean current without ever choking the flow.

The Titan is IsoTek's power specialist: three independent high-current outlets, each with its own cleaning network built on the legendary Direct-Coupled circuit. Made for power amps, monoblocks and active loudspeakers that want every ampere the outlet can give.

Why the V5 Titan?

Many mains filters buy quietness at the cost of dynamics – they filter, but they choke the current. The Titan takes the opposite approach: the Direct-Coupled circuit delivers full power at extremely low internal resistance, thanks to up to eight times the standard amount of copper on the silver-plated board. The result is current that's instantly there when the bass hits. At 153,000 A instantaneous (75,000 A continuous), the protection is the most robust IsoTek has ever built into this model – safeguarded via an RCBO system instead of a simple fuse. The name is well earned.

What you hear

Power without effort. On a decent power amp, the Titan reveals a dynamism you feel more than hear: transients arrive faster, bass becomes drier, and suddenly there's more space between the loudest and quietest passages. Clean current acting as an amplifier for the power that's already there.

Who is the V5 Titan for? (and who it's not for — straight talk)

Made for serious power amps – stereo powerhouses, monoblocks, potent active systems. Straight talk: the Titan has exclusively three high-current outlets and no separate medium-current slots for sources. If you also want to cleanly power a streamer, DAC and preamp, pair it with an Aquarius or Sigmas – or go straight for the Sigmas, which combines both in one chassis. For pure source duty, the Titan is simply the wrong tool for the job (and too good to waste on it).

Our verdict

The V5 Titan is the uncompromising high-current specialist in the lineup: three 16 A outlets, Direct-Coupled circuit, the strongest surge protection in the series. The reference for powerful power amps – and the trade press agrees: the V5 Titan carries the hi-fi+ Editor's Choice Award 2026.

Frequently asked questions

What are the three 16 A outlets on the IsoTek V5 Titan for?

For high-current loads: power amps, monoblocks, active subwoofers and loudspeakers. Each outlet delivers up to 16 A (3,680 W at 230 V) via the Direct-Coupled circuit. Sources and preamps are better suited to a conditioner with medium-current outlets.

Can I also power source components with the V5 Titan?

Only to a limited extent. The Titan has exclusively three high-current outlets for power amps. For streamer, DAC and preamp, pair it with an Aquarius or Sigmas – or go straight for the Sigmas, which combines high current and sources in one chassis.

Why buy the IsoTek V5 Titan at HD Zürisee?

Because a high-current conditioner in this class has to fit the chain. HD Zürisee in Wädenswil advises as an authorized IsoTek dealer on whether a Titan on its own or in combination makes sense, and installs on-site on request.
