Thanks for the feedback, Bruce. I was a little concerned about the AM
filter being too narrow for AM broadcast; however, I'm wondering if it helps
with SW broadcast due to better rejection of adjacent stations. How about
the SSB filter? How would you characterize the performance of that one
versus the stock filter?

I have a plain 8600 with all the optional filters and I would not
recommend the Collins AM filter. Due to its "deeper skirt" AM
reception is a bit tinny and more harsh than the stock AM filter, I
find that listening to Milair and VHF aero can become a bit of an
effort after an hour or so. This is even the case with exteranl
speakers, although when it is connected to a Icom SP-20 it does become
bearable.
