Like the old Alka Seltzer commercial says “Try it. You’ll like it!”

Too many “4500” networks and people are getting them mixed up.

4500 Universal
Crites A/4500
Mike/Dean 4500x

All very different.

And the daughter board that works with the existing AA.

I am now breaking in ( about 90 - 100 hours ) the Jantzen Superior-Z capacitors on my type AA crossovers. Can’t believe what a step up the sound can be, crystal clear sonics and the soundstage has expanded well past my rear wall! My K-horns seem ready to take on the best of Wilson or Focal speakers.

I have a set of new-to-me Klipschorn B, 1968 vintage - they have the original A crossovers.
It has been suggested to switch to the AA crossover (for tweeter protection), and it has also been suggested to stay with the original An (for quality of sound).
I know I need to (at minimum) update the caps, but am wondering if I should make the switch to AA or not.

Does anyone have experience with both versions of the crossovers, and what do you think?

Thanks,
HH

A year plus later, I was wondering what you ended up doing. Inquiring minds...
