Haha, Well I had to reduce the gain a bit to make it bearable. If I reduce it a tad bit more, its not audible, but then there isnt the bit of headroom I want with the 701. Using the w10, however, no problem. Maybe I should jsut put a pot on the output and call it a day.
Nate, do you happen to have an OPA627 I could take off your hands? I can't find one, so I'll be using a OPA134 for the ground channel on the MMM.
