Test reports

"Let's say we had a necklace worth 20,000 euros. Then the filter would perhaps enhance the audiophile level by a further five to ten percent" Andreas Günther - AUDIO 09-2022 | AC-4500

"That which cannot be, must not be" is an outdated maxim. Thanks to the upmarket LS-4004 Pure Silver, which proves even the most devout doubters wrong. A new benchmark. Joachim Pfeiffer - HiFi Sound & Music | LS-4004 AIR Pure Silver

The trade magazine Fidelity presented awards for outstanding hi-fi products for the second time.

"It's as if someone had cleaned the window to the music. Sound colors clearly benefit." Tom Frantzen - Stereo 12-2022 | AC-4500

"The three cables enhance an existing hi-fi system costing around €25,000 by some 15%, which is sheer luxury. This is only possible with in-akustik – most competitors can offer nothing approaching this gain." Audio 12-2019 | LS-; NF-; AC-2404 AIR

WoW. Once again this year, one of our AIR cables has made it to the top of the readers' poll. We are simply overwhelmed.

The in-akustik LS-204 XL Micro Air is the most elegant and "neutral" speaker cable in our test, and therefore my top choice.

"I’m impressed by the way their pursuit for perfection never diminishes their vibrancy and authenticity. Greater distancing and lots of air clearly pays off." Heinz Gelking - image hifi | 2404 AIR series

The verdict nobody wants to hear: get two of these cables rather than just one. The source appears faster, the amplifier darker and more confident. A small but clearly-evident upgrade.Andreas Günther - Audio 04-2021 | AC-1204 AIR

"The LS-4004 AIR is one of the best cables we have ever come across.” The analysis is phenomenal." Andreas Günther - stereoplay 01-18 | LS-4004 AIR

"in-akustik’s superb phono cable is a great example of how consistent application of technology can enable a cable to deliver outstanding results." Holger Barske - LP 01-2017 | Phono-2404 AIR

"No cable has ever sounded better, but the price is impressive as well [...] explores the boundaries of what is possible." Audio 02-2020 | LS-2404 AIR Pure Silver

"The in-akustik LS-4004 Air Pure Silver speaker cable is a statement in terms of appearance, workmanship and sound that is hard to beat." Hans von Draminski - Fidelity 03-2019 | LS-4004 AIR Pure Silver

The LS-1204 AIR is not cheap, but due to its optimized performance (thanks to its extremely low capacity) it is a sound recommendation for audiophile connoisseurs." Michael Voigt - HiFi-Test | LS-1204 AIR

The gain is small, but perhaps decisive for the fan. Above all, the experience is enhanced across all components of the chain. Andreas Günther - stereoplay 02-2021 | AC-4004 AIR

“This in-akustik cable performs its analysis to perfection. You can almost feel the pianist’s breath, drilling deep down into the farthest corner of fine dynamism." stereoplay 09-2016 | Phono-2404 AIR
