anyone compared the bigger Xindak XA8800 MN with the mini XA8800MNu?

I have a pair of the bigger Xindak XA8800MN and love them.  I might be interested in the smaller XA8800MNu for a secondary system.  Anyone here heard both to compare?  Sources include Consonance Droplet 5.0 and Modwright Oppo BDP 83SE w/outboard tube power supply sans preamp.  Speakers include VMPS RM1, Meadowlark Heron hot rod version, BG Corp 520DX, and Triangle Stratos Luna 260.  Thanks for the help.
