I did a cursory search for a thread here about this, but didn't find one. Maybe it's just spread out into other similar threads IDK? But, if someone here knows of a thread that goes into more detail on this subject, I'd appreciate a link?
Since I have an older Marantz AVR, it only has the various DPLII(X) types; but I do find them valuable because they seem to really focus everything towards the Center, which is great for TV /Movies with a lot of conversation/dialog etc and those pesky Brit. shows.
But also feel they're pretty crappy for 2 channel Music up-mixing.
So apparently I've missed this whole DSU controversy. Amazing to me that Dolby would put out a version to remove "Center Spread" and later walk it back and probably had to send updates to correct it back (you'd think they would have been savvy to that in the first place!)
Per the article above:
""Center spread" allowed the listener to preserve stereo imaging from the front channels for 2CH sources. Without it being engaged, too much common sound from the FL/FR speakers is sent to the center channel making the end result too narrowly focused sounding and artificial to most listeners."
So the
"Center Spread" option sounds essential to me to get the best up-mixing for stereo sources for music.
So what I want to know is, on these newer AVR's, can you set up specific personal "trim" adjustments that might actually replicate more of the DPLIIx, and save it as a pre-set for instances where it might actually be an improvement (i.e. enhance the center for speech etc?) I also realize that the DSU update is primarily focused on up-mixing to more of an Atmos speaker array.
