mackie digital x bus
have you used this board first hand? seems like mackie has only sold 2 or 3 of them worldwide. no one seems to have one.
as used by snoop dogg, ac/dc and me! Although I'm pretty sure some other people use them too..
The work flow on this thing is better than an analog board. YMMV.
I use external converters so sound quality isn't an issue, although the built in ones are quite good anyway.
It can run VST's and have UAD cards installed inside it, ie the best eq's and comps you can get in a digital mixer (again YMMV).
72 channels, plus a controller layer, dual touch screens etc..
Being a digital thing there are some issues though, eg if you want to do over 48k you have to use AES cards not ADAT. These issues are getting ironed out though with new updates.
Someone was selling one a few days back in the for sale forum
full disclosure: I've got a "noted user" endorsement deal from mackie, but only because they found out I was planning on buying one anyway.
