Have you spent some time listening to the M19's Jeff? I'm sure they could use some new caps. Maybe you could tweak them to your liking. I don't think a recap and some bypass caps would hurt their value.

Since you are missing an 802G, you could throw your pair of 802D in there instead. For testing purposes of course

Some speakers have no right sounding as good as they do. Like was mentioned above, these are "last speakers" for some people.

Also did you figure out which woofers you have?
