Review: Well worth the purchase - go get em! - Great speaker cables, well worth the purchase. I have been running these cables for around 1 year - Oddly enough this was the last upgrade I did to my setup and I know what everyone says "golden ears" but they actually did make a good improvement to the overall sound quality. ... perhaps I should of bought these first!? ;-) Review: Great improvement very unexpected - I did honestly think they would not live up to expectations,......however I have a mid range linn /Naim system which in all fairness sounded pretty good before the cables arrived . I fitted them and had a listen and omg ! There is so much more going on the bass has tightened up but with my old ears the main thing I was looking for was more info in the mid top which I have got, the depth of the sound stage has doubled ! wish I had got 3.5m as the right speaker lead has no spare . I am running a vintage pair of naim SBL’s. I say .. great value and it does not break the bank . ## Features - As befits a company rapidly closing in on its fifth decades at the forefront of speaker cable design, QED’s brand new XT40i speaker cable builds on the formidable reputation of the XT40 cable it replaces and offers a decisive step up in sound quality. - Air Gap dielectric increases the separation of the conductors inside the cable, and therefore the amount of air between them, QED has created a low-loss Air Gap dielectric. This technology halves the dissipation and capacitance characteristics of the cable, and results in numerous audible improvements - particularly where timing and rhythmic accuracy are concerned. Despite this increased separation, though, XT40i retains the sort of cross-sectional area that makes it ideal for long cable runs. - X-Tube technology Forming the cable conductors into a tube-like shape around a hollow insulating rod in the centre of the cable equalises current densities, delivers very low inductance and presents a consistent, even load to an amplifier. The result is a cable that retains more of the finest musical details, that handles rhythms and tempos in the most natural and musically satisfying way. - Technical Specifications:- Outside diameter: 6 x 14 mm, Conductor area: 4 mm², Dielectric properties: Air Gap (εr = 2.4), Conductor chemistry: 99.999% oxygen-free copper, Dielectric properties: Air Gap, Loop resistance: 8.0 mΩ/m, Parallel capacitance: 35 pF/m, Dissipation factor @ 10kHz: 0.0295, Self-inductance: 0.57 μH/m ## Product Details - **Brand:** QED - **Connector type:** DVI - **Cable type:** DVI - **Compatible devices:** Amplifiers, Speakers - **Special feature:** X-Tube Technology ## Images ![3m Pair of QED XT40i Reference Speaker Cable with X-Tube Technology Terminated with Airloc Banana Plugs (3m Terminated Pair) - Image 1](https://m.media-amazon.com/images/I/81K7aFYRRqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well worth the purchase - go get em! *by T***N on 14 March 2025* Great speaker cables, well worth the purchase.
