I think it's safe to say they're fully broken in, at this point. I still have the tweeter set to flat, and I've decided I like them best with the grills on.
I've been experimenting with toe-in. Those of you who said to pay attention to what's in the manual -- i.e., cross them just in front of the listening position -- were 100% correct. Holy cats! They don't disappear (except with the Perahia recording I mentioned before). Sounds near them tend to stick to them, and I get the sense of things coming from outside them every now and then, but not often. But, man, the stage between them is incredible. In particular, I notice *depth* that I've never really heard before. On something like the Buena Vista Social Club record, I can hear things coming from way back behind the main performers, 3 or 4 layers deep.
I have the fronts propped up on books to give them some rake, which helped a lot getting rid of the feeling I was peering down into the soundstage. They could still stand to come up some, but I'm not really comfortable raking them back any further. I'd like to find some stands -- more like cradles -- to lift them about 4-6 inches and keep the rake angle I currently have. I know this place at least *used* to have several people offering custom woodwork for racks, platforms, turntable plinths, speaker stands, etc. Is there anybody still around who might make the kind of thing I'm talking about?
