Let's face it, before about 6 months ago nobody new anything about auto calibration (this is in reference to the common joe, me). I mean home theater has been around for 10 years or more and millions of owners have gotten by. If Pioneer didn't come out with MCACC, I would have bought a receiver/pre/pro hooked it up and not thought twice. I bet that 90% of the people out there simply hooked up the components and let it rip. Are you telling me all those set ups either don't sound good or are totally out of whack? If I don't buy the 49TX, and hook up something else, will it not sound good right out of the box? thoughts?
