The Concert version highlights the performance of the KLEI™QFLOW ICs (Concert), in that the KLEI™QFLOW ICs (Concert) display a Concert feel/character with a real, organic, natural, riveting, and engaging presentation.
KLEI™QFLOW1 ICs (Concert) are the new entry level model, yet are anything but when compared to other cables. The plugs used are responsible for a significant part of the performance. The KLEI Harmony RCA plugs are a story in themselves and the QFLOW1s employ one of the best plugs in this range, the new (upgraded/improved) Pure Harmony RCA Plug, previously only used with the previous, and far more costly, zPURITY ICs. The conductors within the cable are actually thinner but of higher quality. A studied, optimised, and in most cases a minimalist approach to mass actually results in better sound – and better electron and energy flow. The performance of the new QFLOW1 ICs (Concert) is so good that they have replaced the previous first three gZERO2,3 & 6 models, in the previous GZSeries… John Ransley, Totally Wired 🙂
