What's unique about the brand

IsoTek is a hifi brand specializing in power conditioners that use adaptive gating technology to dynamically adjust filtration based on current demand, with their flagship V5 series praised for improving soundstage and clarity. Their power conditioners feature independent outlet design that isolates each outlet to prevent cross-contamination of noise between connected devices.

What reviewers are saying

We read all the reviews. Here's what reviewers feel most strongly about:

  • IsoTek products utilize a direct-coupled design philosophy that minimizes resistance and ensures the connected equipment receives a high-current power supply without limiting dynamics.
  • They are designed with independent power cleaning networks for each outlet, preventing cross-contamination of noise between connected components.
  • IsoTek equipment commonly incorporate KERP (Kirchhoff's Equal Resistance Path) to ensure each outlet delivers equal resistance and power.
  • The brand's units offer comprehensive surge protection, often exceeding 100,000A, safeguarding connected equipment from power spikes and surges.

Our favorite reviewer quotes:

  • "I loved the Titan because everything I plugged into it sounded bigger and more expansive and therefore more expensive and more grand, but also cleaner smoother and more pleasing. So to me these were no brainer products and if someone would have asked me what they should get first I would have said get a Titan, start there because its effect is so large and diverse." (https://www.pursuitperfectsystem.com/isotek-v5-titan-sigmas-10-year-review)
  • "It created the super impressive hifi effect I call the wide opening of the window where you see through the speakers on to the music. You can see through your ears of course the music being played or happening in space beyond the speakers." (https://www.pursuitperfectsystem.com/isotek-v5-titan-sigmas-10-year-review)
  • "Probably no surprise then that the Super Titan and Genesis combination blew me away. It really is quite incredible improving the subjective performance of pretty much any audio component connected to it." (https://www.hifipig.com/isotek-super-titan-and-genesis-mains-conditioner-and-regenerator)
  • "With the Super Nova powering things, the upper midband and top end sounded a lot less metallic, while Tracey Thorn's vocals were less brittle but gutsier; the track seemed less 'digital' sounding, with a more realistic instrumental timbre." (https://www.stereonet.com/uk/reviews/isotek-evo3-super-nova-"The unit's ability to eliminate common and differential mode mains noise results in: Increased spatial definition Improved dynamic contrast Enhanced bass control Cleaner high frequencies More natural midrange presentation" (https://www.theaudiotailor.com.au/blogs/reviews/isotek-v5-elektra-power-cleaning-system-review-the-ultimate-power-purification-solution)
  • "With source components in particular, there can be a dramatic uplift across a broad range of perceived performance criteria, most noticeably in the spaciousness of the soundstage, cleaner less-gritty top end and reduced high-volume listening fatigue." (https://www.hifipig.com/isotek-super-titan-and-genesis-mains-conditioner-and-regenerator)

What's your approach to customer support?

We try to pass on our knowledge to every distributor. They should pass on to dealers, and they should pass on to customers. But not everyone remembers everything. Therefore, every customer can also contact us directly. 

In addition to standard warranty care, we also take care of older devices. We treat each case individually and always try to help. Even if the damage was caused by the user's negligence. We also offer upgrades for older models. We introduce a lot of improvements - for example, the latest models in the PC series: PC-2, PC-3, PC-3SE, PC-4, have 90% new components compared to those manufactured 10 years ago. So every owner of older generation device can upgrade their model to the latest specification.

About the brand

Puritan Audio Labs' PSM156 power conditioner eliminates transformer hum by removing DC from the power line through 52 stages of filtration, and includes an unusually flexible power cord that's easier to handle than typical stiff cords. Their GroundMaster system uses a simple copper rod grounding method to reduce electrical noise, offering a more affordable alternative to similar high-end products.

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

We do not see merit in claiming technical innovations when the science has been known and understood for the two centuries since Faraday, Ohm, Maxwell, Hertz, Henry, et al. defined the behavioral patterns of electricity and magnetism and their interactions. Even exotic-sounding "modern" dielectric materials advancements and conductor voltage treatments, etc., can be traced back well over half a century ago.

Our approach to product design is to apply clear logic, establishing the broad spectrum of aims for the product, then evaluating and evolving practices that achieve these aims.

This is accomplished firstly within the fundamental design as evolved by measured performance, but from there on, the product is shaped and evolved through massive sequences of listening tests over a very wide selection of HiFi setups of different technologies and ambition. Listening to how each design decision actually sounds as affected by the enclosure dimensions and materials, the board layout, component values and their technology, materials, etc. Establishing how every individual aspect influences the final sound of the overall design. It is a long and painstaking process from which there is no escaping if you wish to present a world-class product.

What's your approach to customer support?

We only distribute through specialist outlets with the required skills to guide and assist customers with their purchase and answer normal technical questions relating to usage of our products. In the event that the questions are more uniquely complex, we are always on hand to take over the conversation. Our products are inherently robust and designed for many decades of use. We always stand by our products, with happy users our topmost priority.

What are your favorite tracks for showcasing the strength of your products?

This is ever-changing, but to note is that for older material in a digital medium, the earliest versions before the compression of the loudness wars took hold are almost invariably the best. For 60s, 70s, and 80s music on vinyl, seek out older pressings produced with an all-analogue master tape to cutting head sequence with no digital process stages in between. If there is a digital stage employed, as with virtually all vinyl of recent decades, including "audiophile" pressings, you are better off listening to the digital version directly.

Today's choice of three would probably be:

  • Joan Armatrading – Me Myself I – AMLH64809 – Dynamics, vocal positioning in the soundstage, and overall imaging
  • Tchaikovsky Violin Concerto – Kyung-Wha Chung, LSO – Previn Decca SXL 6493 – Handling of a large orchestra at full belt and the tonal realism in the solo violin passages
  • Fleetwood Mac – Tusk K66088 – "Beautiful Child" – Vocals, soundstage, imaging, clarity, realism, and separation of the individual contributions

What other products pair best with yours?

We need to ensure that our products interface well across the broadest spectrum of components, and we have, for example, in our development room over 20 different amplifiers from Pass Labs Monoblocs, through Krell, Naim, Meridian, Cyrus, Quad, Leak, Sugden, World Audio, Enleum, as well as many speakers and source components.
