Hey, I was thinking of using this cable for my Sonicwave 3.5mm to female rca adapter, to connect to my receiver's multi-channel in. http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10236&cs_id=1023601&p_id=620&seq=1&format=2&style= Or maybe this cable http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10236&cs_id=1023602&p_id=2682&seq=1&format=2&style= I need your thoughts, an sp/dif cable is 75ohm, as this one. However, I read that sp/dif is a specification that has limited bandwidth. However, I don't think the has to do with the type of cable. Did I make the wrong choice?
