I love the arched hallway.
I am also currently implementing a Shawn Byrne design via the pro theater layout and additional consulting. He knows his stuff.
FYI there is a speaker meet in Des Moine, Iowa on April 27th. I am hoping to go but my wife is putting her foot down with all the time and money I am spending on my own room lately. It would quite a drive for you but if you are interested in the JTR Noesis speakers they will be there.
Here is the list taken from this thread. http://www.avsforum.com/t/1460712/central-iowa-spring-audio-gtg-jtr-bamberg-seaton-salk-gr-research
Bamberg Series 5 Speakers brought by Phil Bamberg of Bamberg Audio

GR Research LS6 Line Array Speakers brought by DesertDome
Salk HT2-TL'S brought by me!
Most of the designers will be there which is a pretty rare opportunity. I have met Jeff and Mark and they are cool fellows. The Noesis is also near the top of my list. I had the opportunity to listen to the demo pair that he sent around to a few of us before he actually debuted the speakers. I was literally blown away. I posted my impressions in the thread. I listened to them in the same room as Desertdomes GR Research LS6 Line Arrays which are also flat out amazing with his 8 x 15'' IB array.
One more thing I noticed that Procella is on your list. Shawn is obviously a dealer for Procella. I am not sure if you have ever heard them but the main reason I went ahead and hired Shawn was after demoing a theater with Procella speakers that Shawn did a professional calibration for. It was Randy Bessingers room and my impressions are in the Procella thread. I have never heard a more cohesive surround sound experience in my life. I can honestly say that I did not understand what surround sound could be until I heard the Master and Commander scene in that room.
