If I do add the Totalmix from Multiface via an ExpressCard, how would Totalmix look? The Multiface would have more extensive routing but the Babyface has newer options and processing. Would the two combine on one screen? Or, should the outputs of the BF be routed to the inputs of the Multiface? This would also give me additional ADAT I/O. RME is unique in long term support and firmware updates. I tried using a Yamaha i88x which has very good mic pres, but it has been abandoned like so many other products that depend on updates. It goes in the recycle can.

There are lots of pres with ADAT outs that would serve you well.  You did not list a number of channels desired or your budget - two important criteria. 

As for continuous updates, I personally would not worry much about that.  This is far more important for an interface than just a pre with built in conversion.  As long as you get gain and a digital signal, there is not much to update.  I have used a Mackie Onyx 800F for many years for extra inputs via ADAT, and have never once felt the need to update it.

After coming out of decision frenzy, I finally went between the expensive top end and the middle of the road group. I did not find any real negative comments on the Audient ASP008 so I ordered it from ODYSSEY PRO SOUND for $1400 - the best price I could find. One review mentioned the very good clock it uses so that should work well with the Babyface.

I read that the original octopre had better pres than the new octopre mk2. The price on the Lucient above was without the digital card. Odyssey said they would sell me one with the card for $1750 because of the confusion.
