Hi. Am looking to try some diffrent speaker cable, I have the QED Silver Anni cable at the moment, But i want to bi-wire my speakers now. So am thinking of either buying another few metres of the same stuff, Or trying some diffrent cable. Is there any diffrent sounds in cable??. Chord Carnival Silver Plus Bi Wire like? £40 for 4metres Is there anything else which is good but not anymore than £10 per metre?.
