Based on this particular disc of Orbison music, Black and White Night (one of best concert discs ever
, recorded by an audiophile engineer HERE on Amazon
) with native DTS 5.1 and in *my system*, PLIIx Movie 7.1
- because to me, it expands soundspace with less "bloomy/"stadium mode-like" character, and alters the front soundstage less. The choice depends on personal taste and what one is looking for, of course, but if you are a neurotic audiophile who looks for layers/depth/voice detail & placement nuance in front soundstage, then PLIIx Movie is the best choice IMHO. Also I should add the observed effect might be less drastic with other music discs, and with movies (vs music, where there are constant voice or instrument info in all channels, all the times, that magnify effect).
For example, in one song, Orbison voice in native 5.1 is slightly recessed.
A. With PLIIx Movie 7.1, it at least stays recessed.
B. With PLIIx Music 7.1 at default setting, the voice gets pulled to stronger center. Subtle, but there. This mode in my system also seems more aggressive in the rear.
I very much preferring testing with music (vs. movie) because unlike movie, where a sound may a. appear for a brief second then disappears, b. move around, and c. vary in intensity, with a music disc the center voice is always there and does NOT move around, nor changes too much in loudness. Because we are familiar with human voice, tracking in this case Orbison's voice taught me what each mode does and whether Ilike it.
FWIW, to me, what is most desirable, is of course, native 7.1 over upmixed 7.1; because as mentioned, native is the mixer's intent, whereas, upmixed is an engineer's intent. So what? Well, it's interesting that even if you don't have an Atmos receiver/speaker setup and are at only 7.1.0, Gravity with Atmos
(native 7.1 fold down
) is "better" theoretically than original Gravity (native 5.1
