I'm using an M-200 per MG-1 (similar to the 1.6) and they sound absolutely beatiful...
I've also got a 755 and so far from what I can tell the 200 and 755 sound the same.. so... ideally the 770 should sound fine as well
And here's some more useful information... I had been using them with a kenwood reciever so what I'm comparing it to now is a huge difference, but the midrage is cleaner, and the detail in the highs is amazing....
