I was told from bluejeans cable that they sell speaker wire (not available in their site, though). It is 12 gage belden (don't know the number) zip speaker wire (20ft for $13, 40ft for $26). Can anyone tell me how good/bad this speaker wire would be? Also, would you recommend banana or spade/pin connector for receiver and speaker end? I also want to ask if there is alternative good quality speaker wire (similar price range above)?
