depends on the blu-ray, but for the most part the diffrence is huge. The soundtrack is just cleaner and meaner!

There is a big difference between regular DTS and DTS-HD MA in my opinion. The difference between the core 1.5Mbps DTS and DTS-HD MA is much less apparent to me but I am glad that I can finally listen to DTS-HD MA since it is being used frequently now. I personally only consider the difference between the core 1.5Mbps DTS stream and DTS-HD MA subtle but worthwhile. For those interested with players set up to pass the core stream over optical or coaxial and audio decoding of DTS-HD MA over HDMI 1.3a, a comparison with switching the audio decoder between digital connections should provide a way to compare for yourself.

Not sure what audio equipment you have Chris but I can hear more than a subtle difference with my equipment and my ears. Is it earth shattering difference? I would say no, but I would say it is more than subtle myself. Standard DTS @ 1.5 mbps is still very very good, but better is better and some people have equipment that makes mine look a transistor radio and I suspect with their $10,000+ equipment the difference would be greater still. My audio equipment is only about $3,500.00 excluding the BD player so a $10,000.00 system would/should make everything sound better though. Ahhh, but one day I will be able to tell first hand...maybe.

First and foremost, the OP needs to know that there is a difference between DTS-HD and DTS-HD Master Audio. Titles, as most of us know, in DTS-HD are rare nowadays -- they're mainly concert titles on Blu ray.

As for the "audible difference" debacle, well, that can be the source of flame wars galore depending on the sites you frequent; I always preferred DTS soundtracks on standard definition DVDs over Dolby Digital, and now that high resolution audio has arrived, the introduction of DTS Master Audio has had me salivating -- unfortunately, my first generation Panasonic player won't support Master Audio at all, and so the MA tracks on certain discs are stripped of their "core" DTS track that's baked into them and that's what gets "bitstreamed" to my receiver for playback...

The results? Most of these DTS core tracks perhaps sound a TAD bit "fuller" or perhaps more "aggressive" in certain instances than legacy DTS tracks off DVDs...again, I cannot be certain of the full impact of Master Audio because I don't have a source deck that will allow for playback. I think though at the end of the day, the VISUAL senses with high definition are more "tickled" and "aroused" if you will than the AURAL senses, which usually happens with anything; there's SOME KIND of improvement with the audio over DVDs on the new format, but it's not exceedingly "night and day" so to speak.

A good example is, say, an aggressive mix like the MA track on LIVE FREE OR DIE HARD (Fox)...the "stripped" DTS core stream sounds WICKED on my system -- so I think to myself Can this really get much better?...

An interesting side note, though, about the "DTS-HD" thing...aside from wanting to explain to the OP that there is a difference between DTS-HD and DTS-HD Master Audio, my Panasonic does a weird, if not interesting, thing when "sensing" these kinds of tracks...

The Panny 'BD10A player supports DTS-HD but NOT DTS-HD Master Audio, and so, as I said, it sends the CORE DTS stream when a MA track is selected from a disc. However, in the player's SETUP MENU, the Master Audio tracks are "sensed" and "handled" by the player's "DTS-HD" AUDIO OUTPUT setup -- in other words, when Master Audio tracks are selected on this player from a disc, the settings I have made under the "DTS-HD" audio output section are what controls how those MA tracks are "handled" by the player...perhaps this is just because Panasonic thought to have the deck "sense" ANY incoming DTS-HD sources as DTS-HD (even if they're Master Audio, which the player doesn't support at all) and apply either PCM output or bitstream output...

I KNOW that isn't what he asked -- I wasn't SAYING that's what he asked, I was just OFFERING that understanding of the differences between the two, because some folks new to the hobby are cloudy on the whole DTS-HD/DTS-HD/MA thing, that's all.

Well, subtle to me just means apparent but not great, the meaning is vague and subtle possibly means something different to you than it does to me. If you can listen and hear what you call a great difference, you might have better hearing because you are younger and you certainly could have better speakers and a better amp. My Yamaha RX-V663 at times doesn't sound as good with familiar music to me as my older RX-V2300 it replaced. It was sure less expensive and added HDMI and decoding of the advanced audio codecs and I wonder how in the world they did that. Most of the time I like it really well and I haven't determined if the DAC's are comparable.

I think I could get it right during a double blind test but I read somewhere during the SACD and DVD-A early years that double blind tests indicated no discernible difference between lossy and lossless and again my comparison between 96kHz/24-Bit DTS and MLP indicated a subtle difference at times and no apparent difference at other times.

BJMiller48 offered this statement at AVSForums, I just stumbled on it and haven't tried to track down a summary of the tests conducted again but that is consistent with what I have read previously when I did try to find articles on the tests.

Quote:
I learned from articles in the Audio Engineering Society, as well as a double blind experiment in Home Theater Magazine, that the differences between core DTS and Lossless DTS Master Pro were either indistinguishable or minimally different in properly controlled scientific experiments. In no case could people identify the "better=lossless) codec consistently.
Of course what the average person can hear isn't necessarily relevant to what everybody can hear but the assumption that there will be a profound difference between the core DTS and DTS-HD MA would not be correct in my opinion.
