I'm not sure what the technical differences are between the two, but I can tell you that, to me, Dolby Surround upmixing sounds better than Neural X on my Denon 7200WA.

With Neural X upmixing stereo DTS sources, I've noticed that dialog and other front audio effects occasionally bleed into the surround channels. This never happens with Dolby Surround. In fact, Dolby Surround does such an incredible job of upmixing stereo movies that many of them sound like discrete surround mixes.

I do notice when putting the audio on nueral it seems like the center is louder and possibly the fronts are too , for sure you hear less loudness from the rear surrounds . Is this the opposite you are getting ?

IM gonna do some testing tonight

I haven't noticed a difference in volume level between D.Surround and Neural X. Also haven't noticed any differences in quality when upmixing 5.1 to 7.1. They're both good at that.

I was only describing the differences I could hear when upmixing stereo movies. I was watching Clash of the Titans the other night (DTS MA Stereo), and noticed that Neural X was occasionally letting some of the dialog bleed into the rear channels, which sounded quite unnatural. Dolby Surround never does that.

Dolby Surround extracts ambient (uncorrelated) content from the base layer speakers, so the overhead sound is more about extending diffuse immersion overhead vs. trying to pinpoint effects. DTS Neural:X extracts correlated sound, so you'll get more precise "discrete sounding" effects moved to the overheads. Compared back to back, Dolby Surround will sound more "spacious" whereas DTS:Neural:X will sound more "aggressive" and "discrete" (ie. more audio coming from the height speakers).

Just pick the mode that sounds best for you. Realize what sounds best may change - sometimes one is better for one movie and another is better for another movie. They both do similar things and since you have both, it doesn't hurt to try.

What worf said,
you can read about this, just google for "dtsx-vs-dolby-atmos-part-ii-dolby-surround-vs-dts-neuralx"
the link from rantingsofamadaudiophile is it, i cant insert links right now, need more posts ;)
i personaly use mostly DTS Neural:X, especialy just for watching standard TV.

You can only use Neural:X only for DTS-HD Master Audio and DTS:X right?

And you can only use Dolby Surround for Dolby TrueHD and Dolby Atmos correct?

For example, can you use Neural:X with Dolby Atmos or Dolby TrueHD?

On early receivers, they limited you depending on the incoming format. A while later, they let you use either regardless of the sound format.

I've watched some old 2.0 mono movies with Neural X engaged by default (since the movie was DTS-HD) on my Denon X6300 and it was almost as if I had turned on 7 channel stereo. I'm not sure what it's trying to do with these movies but, I am not a fan. The effect is very distracting. Dolby Surround leaves these films alone so that they sound like a mono movie should.

Aside from what kind of material these upcoders produce, they appear to EQ material differently, with Neural X (and others) imposing what sounds like Room Gain type EQ on its material. Dolby Digital, to my ears, has a neutral tonal balance.

On my new Yamaha AVR, which offers several surround modes (many of them unique to Yamaha), Dolby Digital is consistently the least intrusive and most subtly effective. Neural X's EQ seems to affect all channels and degrades the articulation a bit.

For old mono movies where DD upcoding is inactive, I find that Yamaha's "Munich Hall" DSP adds a little depth via a subtle form of slap echo that mimics being in a cinema pretty well.

I understand this is an old thread, but thought I give my thoughts anyway. Obviously, it's personal preference between either Dolby Surround or DTS: Neural X as with which is 'better'. My personal preference is Dolby Surround by a considerable margin. That's not to imply that Nueral isn't any good, but I've found that Dolby Surround is more balanced, nuanced, and natural. I tested both in certain key scenes (which I chose) from 'The Predator' (pretty naff movie, but reference sound design). Without going into a long treatise here, in summary I personally find that Dolby Surround reproduces ambience and music better by expanding the entire sound field upwards, thus placing ambience more naturally around the sound stage and making it feels larger and more spaced out (in a good way). Individual effects (or 'objects') that are supposed to be in the height (I use 7.2.4 in ceiling speakers) are also accurately placed as well. For example, in 'The Predator' at around the 34 minute mark, a shotgun blast is fired within the bus directly upwards and the shot and reverberation is well established and cleanly heard using Dolby Surround. Conversely, Nueral X normally places only key sounds or objects with it thinks out to be placed above in the height channels and virtually ignores ambience and music expansion. Also, I found that with Neural X, the soundstage becomes more unnaturally aggressive to the point of being offensive, and that the LFE's from my two subs (dual calibrated using Audyssey Dual Sub EQ) are also unnaturally pronounced, aggressive, and less balanced/well integrated into the sound field. And using the previous case in point about the shotgun blast in the bus, that Nueral X was considerably more aggressive but, but again felt unnaturally so within the sound field. With Dolby Surround you can hear the shotgun blast and the reverberation upwards perfectly loud and clear but simply sounds more natural and not as forced as when Nueral X attempts the same thing.

For me, I'm noticing on my x2400 that Nueralx sounds brighter than Dolby surround.

Stop calling it Nueral, it is Neural.
