I used angled silicone stands for my M5HP and treat them as floor standers. They're angled upwards 15 degrees to eliminate the floor bounce, and you need a pair for each M5HP. They're a perfect fit (I'll upload a photo once I update my gallery pics.)

For some reason, they're only available on the Canadian Amazon site. I can't tell if they are knockoffs of the Audio Engine DS1 stands or if they're the same manufacturer but rebranded.
