Yes. I have Transformers 3 and MI:Ghost Protocol. I put them on, took a listen and immediately thought this sounds like Dolby TrueHD, especially the T:3 track. I opened up the audio menu and sure enough......Dolby TrueHD, we meet again. So many movies have been using DTS-MA that I thought I had heard the last of Dolby THD, but, alas, it turns up like a bad penny at the worst time. I know that DTS tends to be recorded at higher volume levels and that probably does give the perception of sounding better; however, with Dolby TrueHD tracks I have to crank the volume to 70 to get even close to DTS-MA. I don't want to have to crank a receiver up to the bleeding edge of distortion to get something that has some punch. Dolby THD tracks at something reasonable, like 55 - 60 on the dial, sound like they have a wet blanket laying on them.
Also, I cannot see uprezzing a 48 Khz track to 96 Khz as having any noticeable effect in quality. If it was recorded at 48Khz then everything that is there is there. As I see it, taking a 48Khz track and redoing it at 96Khz isn't going to add anything except a lot of artificial interpolation. It isn't bringing out new information because there is nothing new to bring out. It is just adding a lot of useless processing.
Take a listen to Cloverfield, it's Dolby TrueHD 5.1, no need to turn the volume up, earth shattering bass and a very nice surround mix.
Perhaps like me you like the bass in soundtracks to be a little hot, i was actually disappointed in the bass of Abrams take on Star Trek, i adjusted the volume upwards and hey presto it did improve things considerably but i decided to leave at the usual volume ( -10db below reference ) for review purposes, that one was also Dolby TrueHD.
Cloverfield was superb and Star Trek was just very good at the same volume levels, from that i would take it that it's all in the mix and maybe the sound engineers wanted it this way, increasing volume will always give a perception of better ( just louder ) bass, but you have to be careful because the bass could end up dominating the soundstage and sometimes its not how it should be, i'll give you another example, this time a DTS-HD Master Audio track, X-Men Origins: Wolverine, i thought Wolverine didn't have as much bass during some of the action set-pieces as i expected, i put it down to the fact i probably like my bass channel sounding hot but the mix on that film was excellent in all regards except the bass channel, it was very good in the bass channel, it just wasn't reference to me.
Therefore to me it has nothing to do with the sound codec, it has everything to do with the mix and what the sound engineers were going for.
