Your question is a bit like asking: will I regret buying a Mercedes 600? If you can afford it, the chances are you will love it, and have a wonderful, long-term investment. (I look at all Mark Levinson products as an investment.)
The only issue I'd raise regards the mating with the Maggie 1.6's. The 383 is a lot more amp (in terms of quality) than the 1.6's really need, although the Maggies should shine with this pairing. Over time, your listening interests may be best served by upgrading the speakers -- maybe to the Maggie 3.6's if you want to stay with electrostatics.
To be honest, I have never lived with a Mark Levinson amp -- only listened to them in dealer rooms, and with a friend who owns an earlier model. I have, however, followed ML products for more than 30 years as a serious hobbyist, and they are certainly in the Mercedes-Benz 600 class.
