THX Certified - Obsolete today ?

[JimPullan]

With the advent of High Definition displays and high resolution audio, is THX certification products a thing of the past? In the past, those who wanted a THX level certified theater room had to have all THX certified products, the display, the DVD player, the audio components, and the speakers, to ensure they experience, in the home, that which they experienced in the theater. Being that we are at a much higher level of enjoyment experience, are these THX certified products worth the additional expense? and if so, why? What does THX bring to the table now that enhances what we're presently enjoying? You insight, and expert opinions will be greatly appreciated. Thank you in advance for your thoughtful responses.
