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

If you can use a passive Hattor makes excellent products at reasonable prices

Here you go,  I've sat in front of this pre many times,  always found it musical and enjoyable.  
Coda 07X.... New List price is $6500,  I've seen them used for half of that. 

timlub, thanks..... it is very attractive. The Music Room and US Audio Mart had it used awhile back. I'll keep an eye out

Marantz has several models in a mid-fi category.  I've had the AV7005 and now the AV8801.  They seem to have done well with the (discrete) circuitry.  I'm pushing the signal through a couple Parasounds for stereo and HT listening into some Martin Logan Motion series and they are quite clean.

“The Mac C47 does meet the criteria, however it is out of my price range”

Actually, if you look at the C47 carefully, it looks like the two pairs of the XLR outputs are shared with the two pairs of the RCA unbalanced outputs which seems to imply that you can only use one or the other and not both at the same time. So technically it has three outputs one of which is “fixed” similar to a “tape out” loop connection. If you need four independent outputs all of which controlled by the volume control, then you’ll need to look further.
