David, interesting, because I have been thinking just the other way - more boxes. Why? This technology is changing so fast, my theory anyway, is that maybe I don't have to spend as much if I only have to upgrade one piece and not the whole enchilada when a new chip comes out for one component, or something like that.
Who knows? I guess it depends if the system is HT only or combined and weighing out all the options (resale price, IC's, rack space, etc) it's a wacky hobby, eh?
