I will shortly be adding a Velodyne CHT-10 to my system and was wondering what would be the best type of cable to use. Would a dedicated sub. cable like the IXOS 1141 be a better bet than a standard interconnect cable like the QED Qunex 2? (I have seen both of these on sale as sub. cables) Also, I saw one model on sale (another IXOS, can't remember the model) with 1 phono at one end and a Y-splitter and 2 phonos on the other end, with the retailer claiming that as most subs have dual phono inputs, the best performance will be obtained by feeding the signal to both of these inputs. Is this right, or should it not make a difference?
