The Concert/Concerto version highlights the performance of the KLEI™QFLOW ICs (Concert/Concerto), in that the KLEI™QFLOW ICs (Concert/Concerto) display a Concert feel/character with a real, organic, natural, riveting, and engaging presentation.
The following quote is from the many reports that we have received…
When the cables arrived from Australia, our first listening was the combination of the QPURITY∞∞∞/III ICs and QPURITY∞∞∞/III AC/PC. For the second listening the KLEI™QFLOW7 ICs had to be switched in place of KLEI™QPURITY∞∞∞ ICs together with KLEI™QPURITY∞∞∞ AC/PC. Here is a comparison (based on my/our memory image) with KLEI™QFLOW3 ICs. The already very good KLEI™QFLOW3 ICs (and moderately priced) has a “sibling” in KLEI™QFLOW7 ICs which of course is an (even) better cable. Whether it will be able to match KLEI™QFLOW3 ICs in terms of price and quality is a question that I/we today cannot answer.
All cables tested so far are highly recommended (see also previous reviews). It is possible to choose from KLEI’s range (from the very reasonably priced entry level cables to the signature level cables at the top of the range) which are very affordable when compared to other cable manufacturers corresponding models!
May be that our review does not fully give a fair judgment (read; deserves additional superlatives) because we have restrained in our impressions/views of our experience but the thing is that the cables are outstanding cables (read; without competition when both price and quality are taken into account)… Tim & Christer 🙂 🙂 🙂
