Thread: Should you upconvert all DTS, DD 5.1 to THX 7.1 if you can ??

This is a best practices question....

I use an Onkyo 989ver2 THX Ultra certified receiver to drive my Jamo 7.1 THX Ultra surround set-up with two 400w subs and I was wondering what the best practice is (or if it's just preference) for processing DTS and DD signals. Should you always reproduce the soundtrack in it's original format ?? or, upconvert it to THX 7.1 to take advantage of your (my) setup ??

There is obviously lower volume output with THX due to the break-out of the extra two channels which is noticable, but the all around clarity of each of the channels seems to be better with the THX setting than with DTS or DD (especially the center channel dialogue channel).

Anybody have any experience with this situation ??

Go to post #63, maybe that will help you decide. Bottom line, do what sounds best in your home theater with your gear; but THX is not a recording tech or sound field or an up-conversion of anything.

Take advantage of your setup. I don't believe your unit has PLIIx, in which case I would use THX ultra 2 cinema mode for all sources except unflagged DD-EX movies. In the case of unflagged DD-EX sources switch to the THX surround EX setting.

There should also be a THX ultra 2 music mode for music sources.
