I am asking this as a warrior type of question to see what is known in this forum out there. Nowhere in this thread I ask that one bring in the cheaper stuff. This is not intended to be an advice to buy thread. What I am asking and wanting to know is what is the state of the art in equipment and what you have seen even if way out of your budget. Cheap not a goal here. To start off as an idea and example, from what I have seen in Audio Science Review and other places for a reference stereo system setup for noise floor and quality one would be hard to pass up on the combination from Benchmark media
Benchmark Media Systems, Inc. and THX, Ltd. have partnered to introduce the Benchmark HPA4 headphone/line amplifier featuring THX Achromatic Audio Amplifier (AAA™) technology. Featuring the flagship THX-888 amplifier design, the revolutionary HPA4 headphone amplifier incorporates the same...

And from Audio Science Review we have the following measurements
This is a review and detailed measurements of the Benchmark HPA4 headphone amplifier and preamplifier. The company was kind enough to loan me one for testing. The HPA4 retails for US $2999 so not cheap. It is a collaboration between Benchmark and THX to implement the "888" standard. Will it...

and the related DAC (not the exact)
This is a review and detailed measurements of Benchmark DAC3 and headphone amplifier. The unit is on kind loan from member Dallasjustice and is highly anticipated evaluation by myself and I am sure many of you. As of this writing the DAC3 retails for USD $2195 from Benchmark site. Others...

In my honest opinion this the best stereo setup based on the measurements that everything else is measured by for stereo. Amrin in summation says that for the HPA4 and the AHB2 amp that these components for what they are have the lowest noise floor he has ever seen. And the DAC is also good in actively dealing with inherent distortions caused by the digital to analog conversion. I would invite more reading on the links provided.
As I reiterate above, this is an example of what I am looking for when an AVR is postulated. As the stereo example was easier for me to give, this should be an idea of what I would like to see in this thread. I want a thorough discussion of each AVR and links to where the best reviews and measurements are given.
Now for room correction the examples I have been able to find to date on this are as follows
Audessy
YPAO
Dirac
Anthem room correction
Trinnov
And I am certain there are others. I know we have favorites, and many times we also are on a budget, unless we have gotten real lucky and have either won the lottery or married money (that is definitely not me). We all have our favorites, this is not that kind of thread. What I am looking for if you all can dig it up is what you have found that intrigues you. What you have found that seems to excel over other stuff in the category, and point to where if possible the unit has been reviewed and measured if possible by someone 3rd party. And it would be helpful to someone else reading to point a link to the manufacturer web page for the device you are discussing. As in the stereo sample above, I only found this recently and if I were to upgrade my stereo system connected to my computer, this would be something I would consider. In this thread do not worry about budget, lets find the best of the best if we can and have fun doing it.
