Eden was purchased by US Music in about 2002, David Nordschow left a year or so later as he disagreed with US Music trying to shift production to China - you could almsot view it a bit like the GIbson effect on Trace Elliot.
David Nordschow now has his DNA line; Marshall bought Eden last year and I have seen rumours that David is back working in a consultant role for Eden. If that's true I don't know what will happen to the DNA cabs.
Certainly hope Marshall bring them back properly, I do like their cabs and still rate the WT550 as the best SS amp I have ever heard. To be fair I think their "clasic" preamp was developed by James Demeter though, wasn't it?
