(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).
Well, that explains that!
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.
I'm not sure if I would call collapsing the sound into the center "good imaging", so I am not sure I have much of an alternative.
;-) I think a theoretical moderate use of a center would be an improvement, but you're probably right that this is the best answer.
Or, start buying all of my music in 5.1 format. :-) (Still a poor selection, IMO.)
and there were no changes to the 1050 during its production life that would affect your unit.
Actually, early 1050's had a bug which caused the extra DSP modes (Jazz, Hall, etc.) to sound the same as Surround. Mine seems to have this bug, but normally I do not use DSP modes. (All of them I've heard really just make a mess of the sound and are annoying!) SO, I guess what I was wondering was whether or not Natural would treat the steering logic and use of the center channel differently than Surround.
The collapsing to center is a characteristic of Pro Logic, no matter whose receiver it is in.
And regardless of DSP mode?
[QUOTE]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.[QUOTE]
Actually, I don't mind PL so much for TV viewing either, particularly since so much of it is mono anyway, or in the case of movies & shows, probably is mixed for DPL.
SO, I don't think it's worth trying to get PLII just for CD/radio. If I wanted further processing, I'd look into a more advanced algorithm.
