Thank you so much for your detailed message, @hjdca ! Thing is that it seems to be one of the very late WP8 ever built, and I’ve been totally attracted by the WP since the 90s. So this would possibly be a one in a lifetime opportunity to purchase them in my favorite color, and in a very, very good shape. They were the "backup" sound system of an older guy whose primary system was an Infinity RS 1B and thus played only now and then. The foam is in great shape, I guess it muss have been kept away from UV etc. I don’t mind working on the parts you mentioned, i.e replacing the foam when needed (I already read it’s a nasty task to conduct, however, I am also into restoring and keeping alive vintage cars and am not shocked by work like that), same applies to the resistors.
The Sasha W/P has a very, very low serial number in comparison and its life barely documented (in contrast to that of the WP8). As I have a strong bios towards a certain perfectionism, regarding the condition I prefer the WP8. I’m going to again listen to them side by side and then see what my gut tells me.
Thanks again!
