Sorry for the necropost but I think people are forgetting some valid points here. First off I want to put a disclaimer, I am not a professional I just read allot and I happen to have DTS Master Audio Suite and run allot of different types of experiments for the testing of audio codecs, transparency, efficiency, size, bandwidth, compatibility, etc.
DTS-HD High Resolution as of now is not just for smaller bit rates but for BANDWIDTH constraints! DTS Master even with a low AVERAGE bit rate the PEAK bit rate can be as high as 27mbps! If any of you have DTS MAS encoder run a high resolution PCM file (like 96khz/8 channels or 192khz/6 channels) then take a look at the peak bit rate graph and you will see that peak bit rate higher than DTS High Resolution can be sustained for a bit, combine that with multiple DTS Master tracks and you have a serious Bandwidth issue.
So yes DTS High res does have a place but it should have had a variable constrained bit rate (much like some forms of AAC) so 754 core with the extension being variable bit rate like DTS-MA but only up to say 2046, 2304, 2559, 3018, 4608kbps, etc. Variable bit rate can sometimes be rough for bandwidth constraints, very unpredictable. 96khz/24bit/8 channels in LPCM is a very high constant bit rate but DTS Master in tracks that consist of varying levels of activity correlating to high and low bit rates (simply put)...... Ill see if I can post some screenshots from my Master Audio encoder so you can take a look at bit rates, settings, etc....
