There are many other factors that THX covers, including now video issues, in AVRs and AVCs. In the audio realm, the gain structure is strictly defined so that you can easily predict the amplification requirements to reach THX Reference in a given room if you know the sensitivity of the loudspeakers. THX-certified amps will also observe the same gain structure protocols so that this is possible. It's not a well known THX benefit, but applies well established engineering protocols from the professional/commercial field.
I know, we all say that we could do that on your own. But that was not so easily done in the home environment when THX came on the scene. Today so many products have adopted that very gain structure despite not being a THX certified product. I used Emotiva amps in a room design that was otherwise all THX-certified products. I verified input voltage with Emotiva. It matches the THX gain structure requirement, therefore I could specify other products with confidence of what I could achieve in the room.
My point is that although THX has kind of sold out in many ways, therefore diluting their apparent influence, they quietly raised the bar for the audio field. One of the reasons that THX is so lacking in influence these days is that so many of their specs have been freely adopted through the products in the industry over the years. Those are no longer recognized as "THX" features.
The biggest torpedo in the water for this and the rest of the new Onkyo line is the omission of XT32. Over on the Home Atmos thread, there is a link to a German comparison review of AccuEQ and XT32. There is no comparison. Marantz and Denon, here I come.
