I just bought a 520 Elite to be delivered tuesday. At lunch yesterday another HT member told me that the only difference between my Elite and the regular Pioneer is the nicer cabinet. He was told this when he worked at CES this month. Is there an ISF or other Tech that knowes if they are the same internally/performancewise ? It wouldn't surprise me if the standard Pioneer underneath was the old 510, and the 520 had newer and better innerds. I sure hope I didn't just pay for cosmetics, but wouldn't be surprised.
