Selden. I guess this is my main question. Will I hear a significant difference in movies in a 5.1 setup between TRUHD, DTS-MA or Atmos.
This is why I ask. When I went from Dolby Prologic to Dolby Digital, I heard a big difference. Then when I went from just the "core" audio to full Dolby Digital and DTS I heard a difference. Then when I went from Dolby Digital and DTS to TRUHD and DTS-MA I heard a difference. This is all still with a 5.1 system. I would say that each change was worth the price. In a 5.1 setup, will I hear a big enough difference to warrant upgrading to Atmos.
*I* think so, but I think it would be appropriate for you to experience it yourself to find out if it's a big enough improvement for you. There might be an A/V store near you which has set up a room to demo it. (Unfortunately, many of them aren't set up correctly. There have been horror stories about how bad some Best Buy/Magnolia stores are.)
It seems like I could do the Atmos audio if I get an Atmos preamp and upgrade my Jriver. Now upgrading the preamp won't happen soon but when there are more, good Atmos titles, I would upgrade Jriver so I could at least get TRUHD with my 80.3.
TrueHD has been around since the beginning of Blu-ray and DVD-HD production, so I'd be surprised if your copy of JRiver doesn't support TrueHD already. It's just the newly added Atmos component that older versions of JRiver has difficulty with.
If you don't already have some movies with TrueHD soundtracks and want to test TrueHD (with or without Atmos), a variety of "lossless" demo trailers are available for downloading at http://www.demo-world.eu/trailers/hi...n-trailers.php
Scroll down to the section headed "Dolby" and look for the entries with "lossless" in the description.
[quote] Then, later down the line, I would think about upgrading to an Atmos preamp. But only if the Sound Quality in a 5.1 system would be noticeably better then what I would have with TRUHD.
It should be noticeable, since, after all, an Atmos soundtrack will make direct use of overhead speakers while a standard 7.1 or 5.1 soundtrack does not. (Although Dolby ProLogic IIz, Audyssey DSX and DTS Neo:X can upmix to use Front Height overhead speakers.)
Titles with Atmos soundtracks contain a standard Dolby TrueHD 7.1 soundtrack which has been enhanced to include Atmos metadata. That metadata describes how audio objects (defined by whoever mixed the movie's soundtrack) move around the room. In order to decode Atmos, current implementations require that you have overhead speakers, so you'd have what Dolby calls a 5.1.2 or 5.1.4 configuration. If you use Atmos equipment but don't have any overhead speakers, an Atmos-capable AVR or pre/pro plays any Atmos-enabled TrueHD 7.1 soundtrack downmixed to 5.1, just as non-Atmos equipment does.
Many movies with TrueHD soundtracks are already available, although most of them were produced in the early days of Blu-rays and DVD-HD. The dominance by DTS-HD MA happened later because of the greater ease of use of the DTS encoder software in mixing studios. (easier -> quicker -> cheaper)
So for arguments sake, are we saying that I could get the new Marantz preamp, upgrade to Jriver 20, plug my server into the Marantz and I would get an Atmos soundtrack?
If so then that is perfect because I will have no use for 4k until long in the future.
Let me know if I have my logic straight guys because I am out of my element here
Selden, are also saying that it is possible to up mix a TRUHD track to an Atmos track? Or any track for that matter? Even the way I would have it connected?
Thanks for the info
Not exactly. Rather, Dolby has produced a new surround-sound upmixer they've given the old name Dolby Surround (to the annoyance of those of us who were around when they first introduced it decades ago). It's being made available at the same time as Dolby Atmos and replaces ProLogic on most Atmos-capable equipment. (I say "most" because Yamaha has managed to provide both ProLogic and Dolby Surround in their Atmos receivers.) The new Dolby Surround upmixer produces effects which sound very similar to what good Atmos soundtracks are expected to sound like. It seems to be particularly effective when applied to soundtracks of movies which were released theatrically with Atmos soundtracks, although most of them have been released on disc with DTS-HD MA soundtracks.
