I has the Pioneer 54TX and have heard that they improved the MCACC even over the 53TX... I have also heard that there is very little difference, at least that you can hear, between what the MCACC can do and using a test disc and RS meter. I doubt that I will ever get one, but since I am still waiting for my speakers to come, I may change my tune since I have no personal experience to back up what I have heard from others.
