I do have thoughts, although I ended up getting the Canadian made CP-700 instead. Separate fully differentially balanced even in the PSU, all digital functions reduced to what is needed for volume control, such should a true preamp be. The rest is taken care of by my PR-SC5509, and even in bypass mode the CP-700's pinpoint accuracy shines through on the mains, which I biamp.
You may be better off getting an SSP-800 as the CP-800 is basically a two channel processor, now with the PSU inside the box, and all sorts of D/A processing inside, bells and whistles that every Middle Kingdgom product, especially if churning out of the Oppo factory (same town in Guandong province), should have.
I also looked very hard at the MBL preamps.
In the end I am very satisfied with my choice and I find all sorts of reasons to play my 2 channel SACDs in the now fully balanced (A1UDCI) minus the amps 2 channel system.
