Blu, there's no way that what you're going to set up won't "work", since you'll be actually be experiencing reality rather than reading rumors and the rehashing of audio mythologies. As the tests show, your 805's amplifier puts out enough power into 4 ohms to reach a dangerously high sound level with your M80s. No luck will be necessary; just listen and enjoy.

Enjoy the music, not the equipment.
