B&W DM2000 electronic time delay& B&W DM580

any one know anything about these such as msrp and quality of the speakers? Also B&W 500 series DM580. I just picked up both of these and haven't really had time to hook them up and mess with them on my tube setup...
Thanks

The dm2000 sold from '78-'86 for $1390 in black ash/walnut and $1850 in rosewood. Saw a few posts about getting them for $300.

Lots of posts about them if you google.

I need a driver for the dm2000. It sounds like it's out of alignment. Anyone got one?

or know where I can get one?
