The convergene of the 626R is not a "one size fits all" procedure.
Brian suggests that the VMPS ribbons converge a foot or two in front of you, while I like an "on axis" position.
These two set ups do require slightly different set up procedures and will yeild slightly different results.
Crossing the Speakers in front of you will require that the pots be run slightly higher (not a lot mind you) to compensate for the off axis response.
Crossing in front of you may also yeild a larger sweet spot when moving to the left and right.
The "on axis" convergence that I like, will make the sweet spot position more critical, but it makes the listening result, more like wearing headphones.
It also allows you to place the speakers quite wide and still have an incredibly full soundstage and lazer sharp imaging, especially in the center.
As I mentioned, you may not have to run the pots quite as hot when using this "on axis" set up. And if it is used in the nearfield, it can be breathtaking in its abilities with the 626R.
I have a special method for "converging" the 626 that I share with some of my clients. It is difficult to explain, but since you are in LA, call post me and you can stop by and I'll show you.
