The new standard in HiFi - Iraser 4 Sigma
The Iraser 4 Sigma should be standard in any high quality system.

Conclusion: The heading "One for all" was chosen deliberately. I don't know of any comparable product like the Iraser 4 Sigma, which can be used in so many different ways and which also has such a strong effect. The depiction is freer, more open, more airy, less veiled, full of plasticity and liveliness. Subtle nuances are handled with the same ease as large jumps in level. Existing dimensions are highlighted. The staggering of the instruments in breadth and depth wins. With corresponding recordings, the listener thinks there is a lot of air (pictured by the loudspeaker, of course). Brass players are portrayed tasting like brass. Anyone who enjoys hearing human voices will get the same good impressions. Voices are sharper, more supple, have more breath and a greater touch of liveliness. The Iraser 4 Sigma should be standard in any high quality system.

Conclusion: Marco Kolks writes in his assessment that the tested hi-fi accessories from Vortex Hifi "are among the useful things that help to increase enjoyment". I'll keep it short and add one more. Unfortunately, I didn't discover the secret of the Iraser 4 during the listening marathon, which is not the purpose of this report. But if we were already at the end of the year and I could award the “Best Buy” for this year, the Iraser 4 from Vortex Hifi would definitely be the favourite.
An afterthought: After looking through my test system, you noticed that I generally treat CDs with CD spray before playing them. I believe that I can save myself that by using the Iraser 4 in the future.
