Recommended Amplification for Maggies 12 & 1.6

Can someone give some recommendations for minimum amplifcation required to drive Magnepan MG 12 &/or MG 1.6 to adequate levels?

Looking for more tube amp based suggestions. Would appreciate comments from exisiting owners with this combo.
this has been gone over many times on Agon - my own experience with tubes on the 1.6 is that Rogue 120M did not have enough power and I could not afford a powerful enough tube amp for them and eventually sold both. I like to play music loudly so if you do not tubes may work for you.
