Hi I'm in the process of rewiring my whole system following the purchase of my new Pioneer plasma. I am going to be hiding the cables away using trunking so I want to get the cable options right from the start. I'm using a Denon 3802 with a Rel Q100E and a Rel Q150E. Is there any discernable benefit from using both phono's inputs on each of the subwoofers? If so I will need to run the extra cables in advance and buy a Y splitter which I could use with the adapter that I already have (so that I have 4 phono's out of the one sub pre-out on the amp). I only really want to go this route if the result is worthwhile. Is it worth using the lo level neutrik inputs as well? What cable is recommended for subwoofer use? I have 2 lengths of 5m Ixos 1081 but need to replace one of them with a 10m length. Is it worth spending in the £60 region or will a £20 Ixos cable do the job just as well? Thanks for your views.
