An outlaw-phile/audiophile apprised me of this:

dts & surround audio formats .

I linked to it and found very interesting findings. Perhaps this has been discussed here, previously, but I've not seen it. Please reply & clue me in if needed.

What they have is material mastered for dts and other formats, including 5.1. This appears not to be SACD at first glance. They do have DVD-A, however. Interestingly they have a deal where you buy two and get another at no cost. Playing dts would, of course, exclude regular CD players, but would play on a current DVD player such as Oppo or others. Should play also on my Sony 955.

Is this something new or has my head been in the sand? Haven't seen traffic on this forum about this. For us audiophiles this is exciting.
