Indeed. But even better than DTS 5.1, is what I'm saying. Seems like that extra channel in 6.1 contributes to stronger, rear virtuals.
Found the following about DTS 6.1 ES... Now, what this means about how a 3.1 system like the CT-100 would make use of a sixth, discrete channel is anyone's guess. All I can say is I think I hear it in there...somehwere... And by displaying "6.1" during playback, it would seem the unit is recognizing and decoding the format...
From the DTS website:
"DTS-ES The only digital audio format in our industry that is capable of delivering 6.1 channels of discrete audio on standard definition content is DTS-ES (the ES stands for Extended Surround). In addition to the standard 5.1 channels, it adds the capability of a fully discrete center surround channel, positioned between your left rear and right rear speakers.
AV receivers that are DTS-ES capable can decode material encoded in both DTS 6.1 Discrete and DTS 6.1 Matrix decoding, as well as DTS 5.1 content. Played back with a DTS-ES capable receiver and a 6.1-speaker layout, a movie encoded in DTS-ES will dramatically intensify the DTS surround effect. You’ll clearly hear sound effects — such as footsteps coming up behind you — along with other sounds that move front-to-back, and from side-to-side behind you. Even with an older DTS-capable receiver and a 5.1-channel speaker layout, you’ll still hear the center surround channel information; it will be “matrixed” or mixed in between the rear speakers. In either case, you’ll get the fuller, more realistic audio that comes with all DTS formats."
And, found this list of dvds with DTS ES 6.1, if anyone would like to see what their sound bar does with these tracks (in red):
