Hun, it certainly seems that THX is headed towards making its own room correction devices. The Utra 2 specs are still only standards THX requires to be in a receiver/SSP in order to attain that stamp of approval. They certainly have taken great steps to allow HT users to experience a cinema like quality. Altec pointed out earlier that THX was ORIGINALLY set up to standardize cinema playback to ensure that the artists intent was met. It also appears that Audyssey and the Trinnov systems are similiar in nature to the THX desire to offset the limitations most of us have in our home theaters due to space and placement of equipment. While the Audyssey system appears to be very accurate fpr analyzing speaker placement and the Trinnov system appears to allow a user to compensate somewhat for poor speaker placement, the THX system wants simply to translate the cinema experience to your home using technologies which will mix/enhance or attenuate signals from various channels of your HT to accomplish its stated purpose of translating the artists intent to the viewer/listener.
