Yes I agree George but would like to get some input from people who own or at least heard unit...
Seems to be the Hypex NC500 N-Cores, if you listen to or read reviews on the Belcanto 600M monoblocks they’ll sound like these with a bit of tube coloration.
The Belcanto 600M’s are still one of the only Class-D’s that have held my attention, but only when it was given the nice "benign 6ohm flat load" of the top Raven Ribbon tweeter in a two way stand mount.
The Maggie 1.7 may not be a good match as they dive down to 2ohms in the highs with high’ish negative phase angle, this sort of load makes things very tough for Class-D, they prefer to see >4ohm
Notice there’s no mention of what the Rogue Dragon can do into a 2ohm or less load.
