Congratulations! Love class D...can’t imagine anything else moving forward...lighter, cooler, more energy efficient... typically less costly...
I have the PS Audio Stellar 300...replaces a Music Reference RM9 mk2...
(Does it sound as good as that (IMHO) world class tube amp? No. However, it comes much much closer than it should ; )
P.S. Liking the idea of saving a small bit of energy too...
