Isotek Premium Powercord – Quick Impression
This cable was purchased after repeated endorsements of readers of this site. Personally I always figured that it was simply a Lapp cable with a coloured sleeve instead of transparent, with custom printing. But this was just a hunch, and hunches have to be proven. So, finally I decided to make a comparison between the Isotek and a Lapp cable that matched its looks quite closely: comparable connectors, screening and geometry.
Even though the Isotek looks much like a Lapp (outside as well as inside), it does sound lots different. There was no Lapp-typical smooth, big, fat sound but instead an upbeat, lively and confident sound. The Isotek has very good bass solidity, speed and articulation yet isn’t the most nimble cable of this test. Its midrange is ok: not shut in nor shouty but also lacking a little in resolution and smoothness. Finally its treble is also fine at the price: not exactly coarse, but many cables sound more more fluid and refined. Compared to a Lapp 110CY it has a more communicative quality but also more dryness and of coarse less creamy mids and treble. It probably does a nice job of opening up the sound in many midrange systems. Overall, at the price, still recommended, but not for me (and my open system).
