Sempaul,
If you want your Proacs to completely disappear. ( which I don't think is possible ) then I would shift over to tubes. I have never heard proacs sound as good as when I have listened to them on a tube setup.
However if your are bent on your direction, you might try the Marsh with your pre. However I would add CJ and Classe to your list if I were you. I think Classe would beat out any of the amps mentioned with your pre. And as they say with CJ " It just sounds right " And both of these companies have been around quite a long time. Service wont be a problem.
Of course in the end you will need to finally take the time to listen to some different amps. Our opinions are based on our listening experiences and our likes and dislikes.
