Everyone is selling their Ayre QB-9 DSD's??

Awright, what's up with this? I know first hand how good the DSD version is okay? What on earth are people going with if they are starting to dump their QB-9 DSD's? Just really, really curious. Maybe they are moving up to DCS or EMM level of stuff? Or, If there is something out there that is beating these that much I would really love to know what it is.
Thanks.
