I've just had opportunity to test some 'Solid Pure Silver with Teflon' speaker cables [forget name, will give that later] against the Nordost Flatline Bi-wire cables I have running into the JMLab Electra 905 standmounts. Having tried lots of favourite tracks and a few forgotten tracks it was hard to be clear about the difference. Then I tried a Dick Gaughan track, "Now Westlin' Winds", and it was plain as your face - with the solid silver jobbies I could understand what he was singing. A folk singer from Scotland, he has a deep, mumbling style which I now realise is quite demanding of hifi - I forget how long since I listened to him live (is he still alive?) - and the speaker cable with no name (yet) allowed a more solid presentation of his vocals. I think I now need to try some violin pieces that might expose any brightness.
