I have a Denon AVCA1SE with 3 sets of component in's and one set of outputs. I have 4 component sources, DVD, Xbox, PS2 & GameCube. Obviously I don;t have enough inputs on the amp. Can I route 2 sets of components through an AV switching unit without jeopardising quality. If I did I'd use quality cables. Does anyone else have this problem.. I hope this is the right forum for this question.. Leading on from this, when I upgrade my PJ to PS, will this have an affect on how I route things. Xbox and GC and DVD are all progressive..
