I'm warming to going around the walls and under the carpet plate which is a bi-wire run of 10M*2. I would need a cable of no more than 5mm, the width of the underlay, and which could be bent to right angles. This, I think, precludes bi-wires. Looking through the WhatHiFi price list, there are only two such 5 star cables listed which may be suitable, the QED Silver Anniversary XT costing £5.50 at 7.0 * 3.3mm - if it can be bent around its 3.3 side - and the QED X-Tube XT400 costing £20 which is a little over at 6mm. The latter would set me back around £800 if I buy equal lengths. Does anyone know of any other quality speaker cables of 5mm thickness?
I've been told that the Nordost Flat4 is only around 0.6mm thickness which would be ideal for a straight run under the carpet but the supplier could not confirm that would stand up to being walked upon. Kimber PLS is 1-2mm thickness but it would cost me £700 and I'm not sure whether I would have to shave a bit off the underlay.
