Bryston vs MBL

Im ready to buy my first set of monoblocks to use with my AR 5SE and Dynaudio Confidence C4.  Ive been waiting for a pair of MBL Reference 9007 to show up on here but none yet.  While waiting, ive been reading up on Bryston monos.  I think a used pair of 7B3 might hold me over for a few years to come if fthe MBLs dont show up second hand.  The 7B3 have plenty power and is predecessors have great reviews.  Any thougts would be greatly appreciated.  If i get Bryston, im sure ill upgrade in next 3 yrs.. If MBL might upgrade in 5 or 10 yrs.
