I'm sorry to hear that you got a bum MMG, but asking people to remove the socks is just not going to fly. Delaminating is pretty rare in any maggie less than a decade old. I did have to re-glue my old III's once, but those old speaker used an inferior glue compare to what they switched to in the 90's. The one caviate in buying a used maggie that I would look for is fading of the fabric due to being kept in the sun. Over-exposure UV can cause delamination as it degrades the glue. You cannot de-laminate the traces by over-driving the speaker as you would blow the fuses.
