I need to upgrade my analog outs from a new bluray to my old processor
I already have a pair of pbj's so I am thinking of just staying with the same brand.

is upgrading to the timbre or hero worth it over the pbj's? I have parasound electronics and paradigm studio 20's and a paradigm center

also can I buy just three for center and fronts don't think I really need them for the rears

thanks
