My dilemma

If they love current, then tube amps could be the better choice. Though, having myself owned 1.7is with a Halo Integrated (mk1), I can tell you it's a good combo and the Hint has plenty of grunt. It won't produce the "bloom" of that MC275, but no SS amp will. You'll trade some tube sweetness for an all-in-one solution that is nothing to scoff at. Those Maggies should also benefit from using the Hint's bass management to cut them off from the lowest octave.

I think the biggest mistake you could make would be going with the Peachtree.

Yes Maggies love current!
I suggest you get high powered SS amp(s). 

I would get a Bricasti M1 Dac which has volume control and remote volume control. Plug that into your Mac. Then I would get a Melco N1 and record your music on that. Then I would download Music Life remote app on your phone or IPad . that will show all the music you have. All your wife needs to do is turn on the Bricasti then the Melco and then the Mac. Open the app, chose an album and enjoy.

But hey what do I know. 

Maggie will tell you that plenty of tube amps are the best matches. The best I've heard them was with big Rogue monoblocks. OTOH, a number of dealers show Maggies with Mac solid state amps...If you are into Mac, that's an option. The big BAT ss amp is an option too, but I certainly wouldn't call it making your system simpler.
Most folks suggest integrated amp when poster graves simplicity, but I would say that most often power amps barely get touched by a secondary user. It's all preamp user interface/experience that makes joy for a secondary user. Cheers,

I would say yes.  A a Parasound Halo amp is not in the same league as the Mac tube amp. However, your speakers like power and high current that the Mac can’t give you. 

Maggies are better served with a strong solid state amp i think. (maggies are tough to drive). I would also KEEP your MAC & CJ and find some better matched speakers, later on.
