Uhm, it wouldnt be very useful to mutilate a Lambda Sig for drivers, as the Sigma Pro already has Lambda Sig drivers. You would want normal bias SR-Lambda drivers, though it seems like such a shame to take a SR-Lambda apart.
For the two Extremer's (Vicki and Alex), it would probably be a good idea if you could take a couple internal pictures within the next couple days, so we have time to obtain any parts that may need replacing.
The LCD2 sounded much muddier and less detailed than your LCD1. I dunno, your LCD1+bass-some brightness+nicer frame kinda = HE-5 for me. LCD2 is much darker than either, along with what has been already said here.
