I keep seeing a pair of Advent Eternity's at the local thrift that need to be re-foamed. They've been there for weeks and the usual vultures haven't snapped them up yet. Do they know something that I don't? They didn't make it to the fantastic Advent Thread (http://www.audiokarma.org/forums/showthread.php?t=126376) so I am guessing that they are too Jensenized to be worth buying? Thanks!
