Mag itself infers '50>1K watts' for 3.7i's.....that's a huge spread.
Start with 100 per channel...can always throttle down, but have some punch at hand. Feeding desires for power is too easy, audio or politic...;)
A, A/B, or D?
A = somewhat esoteric, happy with TT sources, subject to lengthy discussion.
A/B+ = MOR, 'generic', still the default in many ways. $'s vary with bells & whistles onboard....HT is the bulk of the mass market.
D = Subject to the same 'discussions' of A amps, but available to suit any budget with any wattage one could sanely consider, at the limits of current specs on distortion, qualities, erc. Mho, better with digital sources....
Since you're moving from the Maggies' 'backing into' the equipment....between 'sources' and 'driven'....it's a unique place to be. *S*
The best of both worlds will still be a compromise....
