take a look at the www.knukonceptz.com i noticed the speaker cables over there well priced and seems like of high quality, i am thinking of getting the "Karma 12AWG Biwire" to wire my front, and the "Karma 12AWG" to wire my centre since my centre is not bi-wirable...and the "Klear Cable Blue 12AWG" to wire my rear...any opinions on these cables.?.coz i thought they seems to very reasonably priced and how does it compare to IXOS cable.?.at first i was trying to buy some IXOS cable, but their product range seems to be very wide and sometimes i don't understand their cable's specification... for the Karma 12AWG Biwire, when i combining two of the conductor as one to connect to the speaker terminal at the back of receiver, i guess it will be very thick, so can a banana plug accept the 2 12AWG condutor? another question for terminating the wire is, if i was using a screw type banana plug, did i need to solder the cable and the banana plug to make it air tight.?.or i just screw it and its ok? so if you guys knows some other alternative brand, please recommend me, i wish to biwire my front, while the centre and rear will be single-wire...if talking about IXOS cable, which IXOS range you guys recommend.?.
