I have a profigold 10 sub cable that I bought with my Velodyne CHT-10. I have just set the bass peak level on my Pioneer 2011 and noticed a lot of noise in the signal. Either that or the receiver does this deliberatley. Can anyone tell me if the profigold cable (cheap one about £30 for 10m) is RCA or coaxial? Is coaxial better for subs? If so why is it not also better to use coaxial between say a CD player and preamp? Having just aquired a soldering iron I am keen to make my own new sub cable. Can anyone point me towards a suitable cable and connector?
