That's a lot more distance than I would use but then I never have done the set up with as much toe in as you use. Main thing is that it works, plus makes using the remotes a bit easier.....8^)

Stu,
An unobstructed sound-stage is important to those such as myself who want to visualize the orchestra or artists performing in their imagination - something that's quite impossible with the dominance of the central V-channel separators. That's why I started by draping cork over the side of the speakers themselves and graduated after testing to the inner-side location. The three impressive sound benefits are heard equally well using either location so it's a matter of personal preference.
The tow-in reflects a triangular configuration of speakers and listening position each of which are separated by eight feet.

Hmmm...Not sure if I am understanding you correctly. Are you saying with the dividers you are not getting a wider three dimensional soundstage?
That has not been my experience at all. I get a very wide accurate soundstage with great depth. The caveat is that it all depends on the recordings themselves. That can be a major issue. I have long pursued recordings for which the recordings sets ups are known. Mercury, some RCA's, Some Decca's. Audio Quest recordings are also documented and actual pictures of the recording sessions are often published in their liner notes.
For such documented recordings I can hear the microphone positioning, which in my mind, reflects a neutrality in presentation. This of course does not apply to every recording on every label. The more multi miked the recordings, the greater the sonic " confusion" in terms of imaging, particularly with pop recordings.
In the pop world the Phil Spector "Wall of Sound" is a good example. Spector keeps the vocals usually in correct polarity in order to get that sharp central imaging, but then inverts polarity on the background instruments, causing them to sound a bit blurry but very expansive and with a wide soundstage.
Same thing happens with many artists doing duets. The Michael Crawford album has him singing with some great operatic singers (Barbara Bonney).
Bonney has perfect pitch and she doesn't sound quite as good as Crawford because Crawford in in one polarity and she is in another.
Polarity has been the bane of my listening and it literally took me a decade to be able to recognize upon hearing. The vast majority of the CD seem to be inverted for some odd reason. My DDG's and Philips also....Very frustrating until I put polarity switches on my Phono and picked up a DAC with the switch.
YMMV and FWIW
Stu,
This is what I, perhaps mistakenly, understand as the explanation for the dominant benefits:
1. The improvement in solid, detail imaging is caused by the reflection of the sideways-leaking sound waves forward so that they hit the listener's ear instantaneously with direct sound waves with the concentrated force of matched timing.
2. The expansion in sound stage height is attributable to the re-direction of some of the sound waves that leak inwards/sideways off each speaker being heard after reflecting off the top rather than mid-areas of the channel separator.
3. The marked increase in sound purity follows the removal of corrupt turbulence when the sound waves from each speaker are prevented from leaking sideways and meeting centrally before reaching the listener's ears.
You are correct that the whole sound stage is expanded in width but to me it's the least striking of the improvements and not one for which I can offer an explanation. Perhaps you can? As you say, the whole polarity issue is infuriating with CDPs; with servers the software setting is made once per album and then it's no longer an issue.
Hope that more inmates will grab the plywood/ L-joints and build their own panels to enjoy the many benefits of your tweak.
Thank you again.

Even prior to my panels, I had great soundstage width. The panels basically sharpened the imaging within the soundstage and added a great amount of depth. This additional sharpness makes the extreme width information much more audible, in the sense that it is very nicely presented, with greater resolution of fine detail.
Incidentally, I prefer the panels even taller ( I can't in my room as I have low ceilings). You can experiment with placing a short stool under the panels or even placing an open CD case on the top. (I know, I know..... all that work.....). This way certain pieces, particularly choir pieces (thinking Cantate Domino) achieve a truly ethereal quality.
In a way, I guess we are simulating a headphone. Still, I believe the brain beats the sound waves attempting to combine and produce the center image. The brain does a better job at recombining the left-right data. Our mechanical transducers can not simply be made so precise.
Still the interesting thing is the fact that we can actually channel the sound to our advantage, and increase our enjoyment. The thing that freaks me out is that all this information was always in the musical data in the first place...
Not being able to leave well enough alone, I had a very old, tall, three-section room divider that I decided to put to work.
Being aware that the openings allow "leakage," I like it better than the previous room tune-type arrangement.
Stu,Yes, your tweak demonstrates how the brain constructs an internal sound-stage from the sound-waves heard from the speakers and channel-separators. In placing my head in the conventional external sound-stage between/ behind the speakers, the only music left there is above four feet after leaking over the panels from the speakers. There's zero reproduced-sound beneath.
Racks/ other obstructions of convenience against the central back-wall have previously paid a sonic price for disrupting the flow of leaking sound-waves. Now audiophiles can have their central racks, listen to their music free of that disruption and enjoy the other improvements.

Hi Dryginger,
WHat you say make me think to a...horn wich keep the sound in it's throat as long as possible...
Aupiho,
Please note that this is an exercise in traffic 're-direction' to prevent the cause of ongoing sound-wave crashes...
