SS preamps with two XLR inputs and at least four outputs [two of them XLR]

Rowland Corus.

Krell KCT. I know, I owned one.

I have the Pass XP 10 and it fits your requirements, I'm sure other models do too.

The OP is looking for "at least four outputs". I personally haven’t seen any preamps, maybe except for home theatre processors, that meets that requirement. I think most of models recommended don’t either.
Using splitters is an option. Or check the miniDSP thread.

I'm the OP---- re kalali's apt comment: Many of the preamps suggested do not have 4 sets of outputs. 
kalali is correct: that configuration is indeed rare. My  PS Audio PCA-2 does have two pairs of XLR and two pairs of RCA outputs, which I use to drive two main amps [separately] and two pairs of sub-amps. However, it does not have two pairs of XLR inputs, but only one.... thus my search.
In any event, thanks for all the suggestions.... they are much appreciated.
