From what I understand, they are quite different. MH imports Creek, but I think it ends there. The dimensions alone show major differences. Why would a MH amp be double the height for no reason?
I don't think this is a MH/Pro-ject situation. MH also imports some other stuff, like Bellari
Focal, Pro-Ject, Cambridge Audio, Polk, AKG, Bose, Samsung, LG, Toshiba, Panasonic, Apple, AudioQuest, Monster, Sonos...
