i dunno, but i can tell u its not odd for things that pioneer makes not to be on their website , the 1014 never was, but it was on the canadian and UK site. mainly im guessing because if anyone could do a side beside between the 1014 and 52TX elite they might see that they were paying for it to be extra shinny and a output for there computer. i dont know why the 9100 or 9300 are different but it might be because they dont break when the power goes out like the 1014 if that is so then it might be worth the extra money im still trying to figure out what the difference is internaly between the 1014 and the 52, vs the 54TX the face is different and it weights 5 pds more, but for all i know those could be from lead weights all i want is it to not break when the power goes out :frowning:.
