Leon,
I think they've broken in a bit more the last few days. Normally, my system is on whenever I'm home and awake, seeing as my living room pulls double duty as both a HT and music system. Because of my TV dying last week I've been spending more time in our bedroom so the speakers haven't been playing nearly as much as they normally would. But Friday I borrowed a little 13" TV from my dad and brought the 25" from the bedroom into the living room. So to make a long story short, I've listened to them for general TV viewing and listening to music a lot more in the last couple of days than the last week total.
I think the midrange has smoothed out a bit more and the bass is more articulate. Right now I'm listening to them with my Tumult on, Metals set to small and ports plugged. But at lower listening levels I'm just as happy listening to them set to large, with no sub, and the ports open.
BTW, thanks for the kind words. I do my best to help out my customers (or potential customers) as best I can.
