Anyone auditioned ARC Reference 2 Phono?

Does anyone have any preliminary reports and/or listening experience on the new ARC Ref2 phono preamp. I have the ARC PH7 - a very good phono preamp - but I would like additional gain for my low output MC cartridge (Transfiguration) and I wonder also if the balanced output of the REF2 would give the combination a bit more oomph.
