This might sound silly but it is a simple question. For the members with THX Ultra / Ultra 2 processors and poweramps: do you turn the processors to THX for a THX certified film e.g. Terminator 2? I know THX is post-processing and intended to sound more like your local Odeon but what are its advantages? I do not have THX certified speakers and this maybe why I am not getting the best out of THX.
