I am sure this question has been asked allot but I really cant find a good answer to it. I use the WD LIVE TV PLUS to play my media and I know the WD LIVE TV PLUS does not play DTS MA but it does play the DTS Core. My home theater is a 5.1 Denon Surround Sound and it is able to play the DTS MA. My main question is can anyone really tell the difference between the DTS MA and DTS Core?

AFAIK, the full answer is "it depends." But in general, bluray lossless core is encoded at the highest available bit rate, and is said to be nearly if not entirely indistinguishable from the original PCM. Although that bit rate has been available all along, DVDs generally used a lower bit rate and is easier to distinguish from the original. The MA (lossless) version is said to be bit for bit identical to the original PCM.

I am sure this question has been asked allot
A: Yes, this is a sample of the them:

http://www.avsforum.com/t/823431/new-lossless-audio-vs-the-old-dd-or-dts

but I really cant find a good answer to it.
A: For factual info there is dts website. For subjective opinion there's no single clearcut or unanimous answer.

My main question is can anyone really tell the difference between the DTS MA and DTS Core?
A: See above, but the little info that I can find on wd website it's really dealing with the 'low bitrate' dts from streaming media files rather than Blu-rays.

Audiosceptics accept audio trials using 25 people. A recent Oxford study with over 353,000 patient records from 639 separate clinical trials shows for every 1,000 people taking diclofenac or ibuprofen there would be 3 additional heart attacks, 4 more cases of heart failure and 1 death every year.

DTS Core refers to a portion of the DTS-HD Master Audio codec. It is lossy DTS Surround, the same codec that's been used for years on DVDs and theatrical releases. But, because Blu-rays have more space, the lossy core is encoded at twice the bitrate normally used on those other media. I am not familiar with WD Live TV Plus, but it seems highly unlikely that the DTS offered on a streaming service comes anywhere close to the bitrates used with the DTS Core portion of lossless tracks on Blu-ray.

I believe most people could not tell the difference between dts-MA and the high bitrate DTS core on Blu-ray if they didn't know which was being played. But, again, it is unlikely that the streaming box is outputting anything close to the bitrates used for the core on Blu-ray.
