Hello. I the the new owner of a Pio PDP-427XD and a 696AV DVD player. I was thinkng of installing some wireless surround system, but to my surprise the salesman told me if i dont have pre-wiring installation its not worth it to have a surround system. Is it true or false? and if its false which surround system wireless always will you reccomend for my PIO ? Take into account i am not a full demanding expert person that wants the best out of his home system, but a descent one that i can enjoy my movies. Also what amplifier?
