Great story - thanks for writing it up! I got a pair of cwII's last week myself but I only had to drive 40 miles each way sunny CA. I would have driven quite a bit farther, though[]
I think I'd agree with your comments on the sound being full and clear in the midrange and maybe a bit reserved by comparison in the treble. Not lacking for treble detail, however, which works nicely, I think. (I listen 100% on a vinyl/tube system)
I'm considering rebuilding my crossovers, too, but I'm just going to listen for a while first. There's a great thread about the cwII crossovers here if you haven't seen it:
