First I am not sure what you mean by "How is an SPL meter going to undo what the room is adding to the recording"?
Having good room acoustics/diffusers along with a SPL meter does help correct room deficiencies.
I was not saying that Audyssey or Trinnov were unimportant.
Dubbing stages use the same Radio Shack analog meter to check the calibration of their speakers each day.
The EARS comment was simply to emphasize that every one hears things differently. What might sound good to you in your HT environment might not cut the cake with someone else.

Bitching is not the reason I posted my opinion about an upcoming "pre-processor" from Outlaw. I believe that I made it pretty clear that I am loyal to Outlaw and was very happy with the performance of the 990.
Anxious yes...bitching???...no.
More like excitement about what Outlaw is going to put on the table.
Thoughts,and opinions is what a Forum is all about.

Thanks Skiman for the information.
