"The Oade Brothers and one or two other shops have started with the Sony RK-DA10 (black casing) and RK-DA10P (gray casing) active input cables and added a passive output. Since the outputs are passive, the voltage the cable will provide depends on the model of recorder you're using. If you use a -D3 it'll be 5.2 Volts. If it's a -D7 or -D8 it'll be 4 Volts, and if its a -D100 or -M1 it'll be 3.5 Volts.
Again: There are no cables that are active (voltage translating) for output."
So... I according to this, I needed an active input 7pin for this to work(which his supposedly was), since the M1 was sending a lower than expected voltage. But then it goes on to say this...
"Remember that if you have a TCD-D100 or PCM-M1, and you need an active input cable, you must buy a cable based on the RK-DA10P with the gray housing; the older RK-DA10 with the black casing may or may not work."
So I guess it could have been the older active 7pin input cable??? Huh.
