Dolby ProLogic IIx vs THX Surround EX vs THX Select2 Cinema - Blu-ray Forum

Which do you use/which do you think is the best? All of them do the same job - convert 5.1 tracks to 7.1.

Official Descriptions-

Dolby Pro Logic IIx expands a 5.1 source for 7.1-channel playback. It provides a very natural and seamless surround-sound experience that fully envelops the listener.

THX Select2 Cinema expands 5.1-channel sources for 7.1- channel playback. It does this by analyzing the composition of the surround source, optimizing the ambient and directional sounds to produce the surround back channel out- put.

THX Surround EX expands 5.1-channel sources for 6.1/7.1- channel playback. It’s especially suited to Dolby Digital EX sources. THX Surround EX, also known as Dolby Digital Surround EX, is a joint development between Dolby Laboratories and THX Ltd.

Here's an idea - listen to them and use the one you prefer.

There really is no right or wrong answer. I have the Pioneer Elite SC-65 AVR. Love it. I've listened to these and have preferred THX Surround EX only because I feel that my rears are more defined. However, BIslander is right. It's all about what you prefer.

Some say anything over 5.1 is overkill. That's not my opinion, but everyone has their own listening preferences. You just have to find what yours is. Keep playing with the settings.
