Hic,
There are no definites. If you are buying new I would purchase the new MB450 in a heart beat. They should be incredible. Also get the new 6.5 preamp. Make sure it is a brand new one as there are some changes. You will then be in hassle free heaven. Those are my biases. I would match preamp to amp in this case as you will benefit from the super balanced topology which is truly superb. It takes the sound up a level. If you don't run fully balanced you will miss out. Also the 6.5 preamp is a sleeper. It is affordable & sounds great. Don't mistake the synergy of the combination.
I haven't heard the ARC so no comment but every time I hear VTL equipment (or Manley for that matter) I recognize their sonic signature & love it.
