B & W 801 S3 Crossover Upgrade

Hello fellow Goners!! I originally posted earlier an inquiry if anybody knows if North Creek Music Systems are still in business. I think I’m going with they are no longer in existence. If anyone knows different, please post your input here. Are there any diy’ers who have either upgraded their own crossovers that would be willing to share the recipe or going one step further, anyone have blueprints/schematics to the North Creek Ultimate or Junior upgrade recipe? Thank you in advance.

I was pretty excited to find this, current,  thread on the 801 crossover upgrade. I was especially excited to read that Sabciu pulled the trigger on the Ebay offering. Unfortunately, it appears to be another dead end, for now. Hopefully someone can shed some light on the subject, soon, because one one my stock crossovers failed.
I really appreciate all of you here.
Thanks for having me,
John

This was mentioned here: "According to Frank VanAlstine, the S2’s had a crossover issue which B&W addresses on the S3."

 

That no-parts mod is explained here: https://audiokarma.org/forums/index.php?threads/b-w-matrix-801-series-2-enter-the-lab-and-get-the-van-alstine-treatment.512873/

 

I employed that change to my II's.  Does it improve the II''s sound?  Not to my ears.
