Hi Sbnx,This topic has been bounced around in several threads. More recently I have been documenting some of the setup steps I have been going through with the Avangarde Trios G3's. But since overall setup optimization is more general I thought I would post some information for the interested reader.
Over on his GY8 website Roy Gregory recently wrote a few pages about the setup of a pair of WIlson AlexxV along with the partnering CH Precision electronics. I have pasted the link below. The discussion starts at the bottom of page 5 and goes through page 8. I think Roy's discussion shines a light on two things.
First is the huge amount of effort some manufactures are putting into getting good sound at a show. It takes a lot of effort for all exhibitors to box the gear, ship it, get it to the room, unbox it, assemble the system to get sound and then put in some effort for a stereo presentation. But some really are going the extra mile in an attempt to illustrate what is possible with stereo reproduction. IMO this should be the norm and we should have fewer shows so all the manufacturers and dealers aren't completely exhausted from this effort. It pains me to listent to a pair of $100K+ speakers and a system the is approaching or well exceeding $500k that really doesn't sound all that great. Then you have the youtubers or reviewers writing about how good some of these systems sound. I am not sure exactly what they are listening to.
The second point he makes is the minute detail that is put into fully optimizing a pair of Wilson AlexxV speakers. For example, very few people and maybe only one person would loosen the gantry to make perfectly align it and retorque to spec. Then using a laser level to ensure that each module is perfectly level and aligned within the gantry. I believe most would simply "assemble" the speaker by putting the modules in place and connecting the terminals. This kind of attention to micro detail is what can really push the performance envelope of a system.

The article also discusses some of the very fine adjustments made to the speakers to get them perfectly aligned to the listener. By this I don't just mean the spike/ladder adjustments for the modules mentioned in the Wilson manual , but rather very, very small adjustemens in the attitude (Toe-in, Rake & Azimuth) of the oveall speaker. A few years ago I posted a survey on what people would consider a small movement to the speaker. Only a handfull of people responded to that and some of the posts following were fairly contensious. I am not sure why this is other than a lack of having the experience of witnessing the result. The answer I would give in the survey is that if you can see the speaker move it has likely moved too far. It still completely baffles me how going over to the speaker and giving it the smallest tap can alter the sound. And not just alter it, but change the sound in a very significant way. Of course this only happens when it gets to the pointly end of the stick in the setup process. At the start of the process movements do occur in increments of 1/2" to 1" but very quickly that drops to 1/4 to 1/16" and then to less than 1mm and then down to the point where one can not physically observe that the speaker moved. The way I relate to this is the higher up in frequency you go the shorter and shorter the wavelength gets. To adjust the time arrival at higher frequencies involves an ever decreasing size of adjustment. Roy is trying to convey this sense of "preciseness" in his article. However, it is very hard to understand unless someone has seen this being done and heard the sonic response.
But one doesn't have to go the Nth degree to get improved results in their setup. Roy wrote two articles about 10 years ago that help in providing a guide for those that want to improve their sound for free. I don't know if anyone has seen these so I am posting the links below. The first is a how-to guide that walks the reader through what the various adjustments are and what the expected sonic response is to that adjustment. The second is a write-up of of a demo he did at one of the audio shows (RMAF). In this article he writes about using a group of people as observers and judges for the sound. He then uses a few music selections and goes through the setup process showing the impact of each move. This process was pretty rough (meaning there were no super fine adjustments) and good results were still obtained.
I can't imagine spending $130K on a pair of speakers and not wanting them to perform at the absolute top end of what they are capable of with the given electronics and room. A lot of audiophiles are stopping far short of achieveing the full potential of their system. Perhaps this is becasue they have not heard a solid reference point. For example, I visited a dealer this past weekend and listened to the MBL extreme system. One of the things I listened to was that same piano section from Beethoven's first piano concerto that I recorded in the youtube video. The piano runs sounded completely smeared. Now, this is at a dealer and not a show. Why are they demo'ing a system that costs a gazillion dollars that has such poor sound quality? Again, I think it is becasue the industry as a whole has a poor reference point and we all have just been accepting subpar sound.

As a note, I have no affiliation with these individuals other than I know who they are and I know their work. No one asked me to write this and I get no compensation in any form. The only intent of the post is for those interested in exploring the posibilites of increased performance through the very detailed process of speaker placement. Although, I will admit I did rant a little about dealers and poor setup of high end system.
Another excellent thread! I got to read it from the beginning.
But a question jumps into my mind right away: how much of the setup is physics to get it to sound right in the room, and how much of the setup is based on personal taste?.
Let's say, as an example, someone buys the new Avantgarde Duo Mezzo. they have have a room that is 21' x 16' x 10', so should accommodate the speakers. If they don't have room treatments, would you recommend them, and come back to setup? and if it's bare, would you set it up in the likely echo chamber?
From a personal taste perspective, someone may want a SET for their Avantgarde instead of the itron. Use vinyl / digital... Or they may want to use cables to use as the tone controls to tune to their taste.... or get a preamp they are acclimated to...
But gear aside, how would you set up the system differently based on their taste?
