It sounds like you are using Pro Logic with stereo sources and are underwhelmed with the results. You are far from alone in that: Pro Logic often struggles with pure stereo sources like CD's, and many people have found it seriously lacking for surround processing of CD's (it relies on the source to include the steering logic to help it break out center and surround signals, so sources that lack that logic are prone to collapsing completely into the center channel). You might consider turning the center channel off and using a phantom center -- it will keep the data in your mains rather than steering it all to the center, although you may still lose some imaging. With main speakers that are so much better than your center, you may prefer a phantom center channel or even just stereo mode for music listening.

The 1050's implementation of Pro Logic is very similar to any other receiver's Pro Logic mode, and there were no changes to the 1050 during its production life that would affect your unit. The collapsing to center is a characteristic of Pro Logic, no matter whose receiver it is in.

For what it's worth, Pro Logic II certainly does a better job with this sort of material, but it still is a computer manipulation of a program that was created for stereo reproduction. I use PLII on my 950 for cable TV and DD2.0 DVD's, but most of the time I still listen to CD's in stereo mode.
