So far I am very pleased with the 563A. I does everything well. I had a Panasonic CP-72A before which did it all except SACD, but it failed on me after only 14 months. I had an extended warranty for one year, and they are replacing it with a Panny F85, basically the same player (changer).
I will sell that one at discount, I jumped at the Pioneer for $179 for the additional capability. Performance-wise I don't see or hear a big difference. Both are excellent value, but the Pioneer has nicer ergonomics and even looks a bit more expensive than it is. The remote on Pioneer looks a bit cheap, the one on the Panasonic is very chintzy.
